Subject: [PATCH 024/877] Added tests in testAHRSFactor and corrected
 AHRSFactor so that it works. added target in .cproject. Note that not all
 tests work. In particular the IMUbias jacobian fails because the dimensions
 of expected and actual are different.

Subject: [PATCH 043/877] The range adaptor scheme did not work for std::map
 TERMS in creating a JacobianFacor. Hence, I removed it - which I think is
 more readable - and replaced it with an explicit creationg of dimensions. I
 also added a test with std::map, which works.

Subject: [PATCH 240/877] Another very significant speed-up of reverseAD
 pipeline, by template specialization of the leaf case for fixed matrices.
 Unfortunately, while this sped up reverse AD for our SFM kernel by 300%,
 reverseAD was only 6%, and is now 2% of total time. So, time to look
 elsewhere. Oh, and, it is clear that the Identity matrix for Leaf only
 expressions is completely known at compile time: Eigen::Matrix<double,
 T::dimension, T::dimension>::Identity(). That should nicely speed up many a
 PriorFactor (replacement).

Subject: [PATCH 253/877] Cached Rot3::transpose(). Inspired by @cbeall3 fix of
 Unit3, I realized that with one million points and 1000 cameras, the same
 Matrix3 (R_.transpose()) was computed a 1000 more times than needed.
 Especially with quaternions this would be expensive, even with Rot3Q.

Subject: [PATCH 254/877] Just always store transpose? Problem with optional
 was that the *empty* optional was copied from the Values, so we gained
 nothing. However, this is expensive space-wise (double), and optimizes for a
 particular usage of Rot3, so does not seem good practice (see stack overflow
 discussion, as well). But the alternative is cumbersome.

+// Computation of the Jacobian matrix for vector-valued functions of multiple
+// variables, using automatic differentiation based on the implementation of
+// dual numbers in jet.h. Before reading the rest of this file, it is adivsable
+// to read jet.h's header comment in detail.
+//
+// The helper wrapper AutoDiff::Differentiate() computes the jacobian of
+// functors with templated operator() taking this form:
+//
+//   struct F {
+//     template<typename T>
+//     bool operator()(const T *x, const T *y, ..., T *z) {
+//       // Compute z[] based on x[], y[], ...
+//       // return true if computation succeeded, false otherwise.
+//     }
+//   };
+//
+// All inputs and outputs may be vector-valued.
+//
+// To understand how jets are used to compute the jacobian, a
+// picture may help. Consider a vector-valued function, F, returning 3
+// dimensions and taking a vector-valued parameter of 4 dimensions:
+//
+//     y            x
+//   [ * ]    F   [ * ]
+//   [ * ]  <---  [ * ]
+//   [ * ]        [ * ]
+//                [ * ]
+//
+// Similar to the 2-parameter example for f described in jet.h, computing the
+// jacobian dy/dx is done by substutiting a suitable jet object for x and all
+// intermediate steps of the computation of F. Since x is has 4 dimensions, use
+// a Jet<double, 4>.
+//
+// Before substituting a jet object for x, the dual components are set
+// appropriately for each dimension of x:
+//
+//          y                       x
+//   [ * | * * * * ]    f   [ * | 1 0 0 0 ]   x0
+//   [ * | * * * * ]  <---  [ * | 0 1 0 0 ]   x1
+//   [ * | * * * * ]        [ * | 0 0 1 0 ]   x2
+//         ---+---          [ * | 0 0 0 1 ]   x3
+//            |                   ^ ^ ^ ^
+//          dy/dx                 | | | +----- infinitesimal for x3
+//                                | | +------- infinitesimal for x2
+//                                | +--------- infinitesimal for x1
+//                                +----------- infinitesimal for x0
+//
+// The reason to set the internal 4x4 submatrix to the identity is that we wish
+// to take the derivative of y separately with respect to each dimension of x.
+// Each column of the 4x4 identity is therefore for a single component of the
+// independent variable x.
+//
+// Then the jacobian of the mapping, dy/dx, is the 3x4 sub-matrix of the
+// extended y vector, indicated in the above diagram.
+//
+// Functors with multiple parameters
+// ---------------------------------
+// In practice, it is often convenient to use a function f of two or more
+// vector-valued parameters, for example, x[3] and z[6]. Unfortunately, the jet
+// framework is designed for a single-parameter vector-valued input. The wrapper
+// in this file addresses this issue adding support for functions with one or
+// more parameter vectors.
+//
+// To support multiple parameters, all the parameter vectors are concatenated
+// into one and treated as a single parameter vector, except that since the
+// functor expects different inputs, we need to construct the jets as if they
+// were part of a single parameter vector. The extended jets are passed
+// separately for each parameter.
+//
+// For example, consider a functor F taking two vector parameters, p[2] and
+// q[3], and producing an output y[4]:
+//
+//   struct F {
+//     template<typename T>
+//     bool operator()(const T *p, const T *q, T *z) {
+//       // ...
+//     }
+//   };
+//
+// In this case, the necessary jet type is Jet<double, 5>. Here is a
+// visualization of the jet objects in this case:
+//

+// A simple implementation of N-dimensional dual numbers, for automatically
+// computing exact derivatives of functions.
+//
+// While a complete treatment of the mechanics of automatic differentation is
+// beyond the scope of this header (see
+// http://en.wikipedia.org/wiki/Automatic_differentiation for details), the
+// basic idea is to extend normal arithmetic with an extra element, "e," often
+// denoted with the greek symbol epsilon, such that e != 0 but e^2 = 0. Dual
+// numbers are extensions of the real numbers analogous to complex numbers:
+// whereas complex numbers augment the reals by introducing an imaginary unit i
+// such that i^2 = -1, dual numbers introduce an "infinitesimal" unit e such
+// that e^2 = 0. Dual numbers have two components: the "real" component and the
+// "infinitesimal" component, generally written as x + y*e. Surprisingly, this
+// leads to a convenient method for computing exact derivatives without needing
+// to manipulate complicated symbolic expressions.
+//
+// For example, consider the function
+//
+//   f(x) = x^2 ,
+//
+// evaluated at 10. Using normal arithmetic, f(10) = 100, and df/dx(10) = 20.
+// Next, augument 10 with an infinitesimal to get:
+//
+//   f(10 + e) = (10 + e)^2
+//             = 100 + 2 * 10 * e + e^2
+//             = 100 + 20 * e       -+-
+//                     --            |
+//                     |             +--- This is zero, since e^2 = 0
+//                     |
+//                     +----------------- This is df/dx!
+//
+// Note that the derivative of f with respect to x is simply the infinitesimal
+// component of the value of f(x + e). So, in order to take the derivative of
+// any function, it is only necessary to replace the numeric "object" used in
+// the function with one extended with infinitesimals. The class Jet, defined in
+// this header, is one such example of this, where substitution is done with
+// templates.
+//
+// To handle derivatives of functions taking multiple arguments, different
+// infinitesimals are used, one for each variable to take the derivative of. For
+// example, consider a scalar function of two scalar parameters x and y:
+//
+//   f(x, y) = x^2 + x * y
+//
+// Following the technique above, to compute the derivatives df/dx and df/dy for
+// f(1, 3) involves doing two evaluations of f, the first time replacing x with
+// x + e, the second time replacing y with y + e.
+//
+// For df/dx:
+//
+//   f(1 + e, y) = (1 + e)^2 + (1 + e) * 3
+//               = 1 + 2 * e + 3 + 3 * e
+//               = 4 + 5 * e
+//
+//               --> df/dx = 5
+//
+// For df/dy:
+//
+//   f(1, 3 + e) = 1^2 + 1 * (3 + e)
+//               = 1 + 3 + e
+//               = 4 + e
+//
+//               --> df/dy = 1
+//
+// To take the gradient of f with the implementation of dual numbers ("jets") in
+// this file, it is necessary to create a single jet type which has components
+// for the derivative in x and y, and passing them to a templated version of f:
+//
+//   template<typename T>
+//   T f(const T &x, const T &y) {
+//     return x * x + x * y;
+//   }
+//
+//   // The "2" means there should be 2 dual number components.
+//   Jet<double, 2> x(0);  // Pick the 0th dual number for x.
+//   Jet<double, 2> y(1);  // Pick the 1st dual number for y.
+//   Jet<double, 2> z = f(x, y);
+//
+//   LOG(INFO) << "df/dx = " << z.a[0]
+//             << "df/dy = " << z.a[1];
+//
+// Most users should not use Jet objects directly; a wrapper around Jet objects,
+// which makes computing the derivative, gradient, or jacobian of templated
+// functors simple, is in autodiff.h. Even autodiff.h should not be used
+// directly; instead autodiff_cost_function.h is typically the file of interest.
+//
+// For the more mathematically inclined, this file implements first-order
+// "jets". A 1st order jet is an element of the ring
+//
+//   T[N] = T[t_1, ..., t_N] / (t_1, ..., t_N)^2
+//
+// which essentially means that each jet consists of a "scalar" value 'a' from T
+// and a 1st order perturbation vector 'v' of length N:
+//
+//   x = a + \sum_i v[i] t_i
+//
+// A shorthand is to write an element as x = a + u, where u is the pertubation.
+// Then, the main point about the arithmetic of jets is that the product of
+// perturbations is zero:
+//
+//   (a + u) * (b + v) = ab + av + bu + uv
+//                     = ab + (av + bu) + 0
+//
+// which is what operator* implements below. Addition is simpler:
+//
+//   (a + u) + (b + v) = (a + b) + (u + v).
+//
+// The only remaining question is how to evaluate the function of a jet, for
+// which we use the chain rule:
+//
+//   f(a + u) = f(a) + f'(a) u
+//
+// where f'(a) is the (scalar) derivative of f at a.
+//
+// By pushing these things through sufficiently and suitably templated
+// functions, we can do automatic differentiation. Just be sure to turn on
+// function inlining and common-subexpression elimination, or it will be very
+// slow!
+//
+// WARNING: Most Ceres users should not directly include this file or know the
+// details of how jets work. Instead the suggested method for automatic
+// derivatives is to use autodiff_cost_function.h, which is a wrapper around
+// both jets.h and autodiff.h to make taking derivatives of cost functions for
+// use in Ceres easier.

+// ARRAYSIZE performs essentially the same calculation as arraysize,
+// but can be used on anonymous types or types defined inside
+// functions.  It's less safe than arraysize as it accepts some
+// (although not all) pointers.  Therefore, you should use arraysize
+// whenever possible.
+//
+// The expression ARRAYSIZE(a) is a compile-time constant of type
+// size_t.
+//
+// ARRAYSIZE catches a few type errors.  If you see a compiler error
+//
+//   "warning: division by zero in ..."
+//
+// when using ARRAYSIZE, you are (wrongfully) giving it a pointer.
+// You should only use ARRAYSIZE on statically allocated arrays.
+//
+// The following comments are on the implementation details, and can
+// be ignored by the users.
+//
+// ARRAYSIZE(arr) works by inspecting sizeof(arr) (the # of bytes in
+// the array) and sizeof(*(arr)) (the # of bytes in one array
+// element).  If the former is divisible by the latter, perhaps arr is
+// indeed an array, in which case the division result is the # of
+// elements in the array.  Otherwise, arr cannot possibly be an array,
+// and we generate a compiler error to prevent the code from
+// compiling.
+//
+// Since the size of bool is implementation-defined, we need to cast
+// !(sizeof(a) & sizeof(*(a))) to size_t in order to ensure the final
+// result has type size_t.
+//
+// This macro is not perfect as it wrongfully accepts certain
+// pointers, namely where the pointer size is divisible by the pointee
+// size.  Since all our code has to go through a 32-bit compiler,
+// where a pointer is 4 bytes, this means all pointers to a type whose
+// size is 3 or greater than 4 will be (righteously) rejected.
+//
+// Kudos to Jorg Brown for this simple and elegant implementation.

 still some segfaults, *and* there should be no need for (a) multiple
 prototypes to match against c++ pointers, (b) the use of explicit template

+ * Note that all of these functions have two versions, a boost.function version and a

+ * a function to fit the correct structure, which is useful for situations like
+ * member functions and functions with arguments not involved in the derivative:
+ *
+ * Usage of the boost bind version to rearrange arguments:
+ *   for a function with one relevant param and an optional derivative:
+ *     Foo bar(const Obj& a, boost::optional<Matrix&> H1)
+ *   Use boost.bind to restructure:
+ *     boost::bind(bar, _1, boost::none)
+ *   This syntax will fix the optional argument to boost::none, while using the first argument provided
+ *
+ * For member functions, such as below, with an instantiated copy instanceOfSomeClass
+ *     Foo SomeClass::bar(const Obj& a)
+ * Use boost bind as follows to create a function pointer that uses the member function:
+ *       boost::bind(&SomeClass::bar, ref(instanceOfSomeClass), _1)

+
+/**
+ * Example of a simple 2D localization example
+ *  - Robot poses are facing along the X axis (horizontal, to the right in 2D)
+ *  - The robot moves 2 meters each step
+ *  - We have full odometry between poses
+ */
+
+// We will use Pose2 variables (x, y, theta) to represent the robot positions
+#include <gtsam/geometry/Pose2.h>
+
+// In GTSAM, measurement functions are represented as 'factors'. Several common factors
+// have been provided with the library for solving robotics/SLAM/Bundle Adjustment problems.
+// Here we will use Between factors for the relative motion described by odometry measurements.
+// Also, we will initialize the robot at the origin using a Prior factor.
+#include <gtsam/slam/PriorFactor.h>
+#include <gtsam/slam/BetweenFactor.h>
+
+// When the factors are created, we will add them to a Factor Graph. As the factors we are using
+// are nonlinear factors, we will need a Nonlinear Factor Graph.
+#include <gtsam/nonlinear/NonlinearFactorGraph.h>
+
+// Finally, once all of the factors have been added to our factor graph, we will want to
+// solve/optimize to graph to find the best (Maximum A Posteriori) set of variable values.
+// GTSAM includes several nonlinear optimizers to perform this step. Here we will use the
+// Levenberg-Marquardt solver
+#include <gtsam/nonlinear/LevenbergMarquardtOptimizer.h>
+
+// Once the optimized values have been calculated, we can also calculate the marginal covariance
+// of desired variables
+#include <gtsam/nonlinear/Marginals.h>
+
+// The nonlinear solvers within GTSAM are iterative solvers, meaning they linearize the
+// nonlinear functions around an initial linearization point, then solve the linear system
+// to update the linearization point. This happens repeatedly until the solver converges
+// to a consistent set of variable values. This requires us to specify an initial guess
+// for each variable, held in a Values container.
+#include <gtsam/nonlinear/Values.h>

Subject: [PATCH 331/877] Removed transpose_. It did speed up things but was

 transpose() overhead. One way is to return a Eigen::Transpose<> object as
 hinted to in comments.

Subject: [PATCH 339/877] using static_cast in GenericValue's virtual functions

should be more efficient, but perhaps will crash instead of throwing an exception when the Value& derived class doesn't match.

Subject: [PATCH 340/877] all values in Values container are now a
 ChartValue<ValueType, Chart=DefaultChart<ValueType> > ChartValues are
 GenericValues and a Chart, which defaults to DefaultChart had to make charts
 functional (ie no storage of the chart origin) so that they could be zero
 sized base class otherwise there would have been a double of the memory for
 values (ones for the value, and once for the chart origin, which default to
 the same)

most tests work, execept for serialization based stuff, and const filtering of values.

 fixed-sized matrices in to develop Expressions. All copy/paste bloat is now
 gone, and boost::none arguments are back.

 MaxVirtualStaticRows is now a macro and some preprocessor derictives activate
 and deactivate the corresponding defintions. This could be of course removed
 at some point.

Subject: [PATCH 803/877] fixed all. Cant deal with conservative resize becaue
 this is dependent on the template dimension. Maybe OptionalJacobian<3,dimK>
 or somehting like that ?

+/**
+ * CombinedImuFactor is a 6-ways factor involving previous state (pose and velocity of the vehicle, as well as bias
+ * at previous time step), and current state (pose, velocity, bias at current time step). According to the
+ * preintegration scheme proposed in [2], the CombinedImuFactor includes many IMU measurements, which are
+ * "summarized" using the CombinedPreintegratedMeasurements class. There are 3 main differences wrt ImuFactor:
+ * 1) The factor is 6-ways, meaning that it also involves both biases (previous and current time step).
+ * Therefore, the factor internally imposes the biases to be slowly varying; in particular, the matrices
+ * "biasAccCovariance" and "biasOmegaCovariance" described the random walk that models bias evolution.
+ * 2) The preintegration covariance takes into account the noise in the bias estimate used for integration.
+ * 3) The covariance matrix of the CombinedPreintegratedMeasurements preserves the correlation between the bias uncertainty
+ * and the preintegrated measurements uncertainty.

-README - Georgia Tech Smoothing and Mapping library
-===================================================
-
-What is GTSAM?
---------------
-
-GTSAM is a library of C++ classes that implement smoothing and
-mapping (SAM) in robotics and vision, using factor graphs and Bayes
-networks as the underlying computing paradigm rather than sparse
-matrices.
-
-On top of the C++ library, GTSAM includes a MATLAB interface (enable
-GTSAM_INSTALL_MATLAB_TOOLBOX in CMake to build it). A Python interface
-is under development.
-
-Quickstart
-----------
-
-In the root library folder execute:
-
-```
-#!bash
-$ mkdir build
-$ cd build
-$ cmake ..
-$ make check (optional, runs unit tests)
-$ make install
-```
-
-Prerequisites:
-
-- [Boost](http://www.boost.org/users/download/) >= 1.43 (Ubuntu: `sudo apt-get install libboost-all-dev`)
-- [CMake](http://www.cmake.org/cmake/resources/software.html) >= 2.6 (Ubuntu: `sudo apt-get install cmake`)
-
-Optional prerequisites - used automatically if findable by CMake:
-
-- [Intel Threaded Building Blocks (TBB)](http://www.threadingbuildingblocks.org/) (Ubuntu: `sudo apt-get install libtbb-dev`)
-- [Intel Math Kernel Library (MKL)](http://software.intel.com/en-us/intel-mkl)
-
-Additional Information
-----------------------
-
-See the [`INSTALL`](https://bitbucket.org/gtborg/gtsam/src/develop/INSTALL) file for more detailed installation instructions.
-
-GTSAM is open source under the BSD license, see the [`LICENSE`](https://bitbucket.org/gtborg/gtsam/src/develop/LICENSE) and [`LICENSE.BSD`](https://bitbucket.org/gtborg/gtsam/src/develop/LICENSE.BSD) files.

Subject: [PATCH 877/877] We will not wrap fixed Vectors and Matrices
 individually. Methods that take those can just as well be wrapped with Vector
 or Matrix. Note const and & are ignored for those. I added a small method,
 insertFixed, that allows one to put in small fixed size matrices for
 optimization. Did not do retrieval yet.
