| Also, GTSAM 4 introduces traits, a C++ technique that allows optimizing with non-GTSAM types. That opens the door to retiring geometric types such as Point2 and Point3 to pure Eigen types, which we will also do. A significant change which will not trigger a compile error is that zero-initializing of Point2 and Point3 will be deprecated, so please be aware that this might render functions using their default constructor incorrect. | ||||

| We provide support for [MATLAB](matlab/README.md) and [Python](cython/README.md) wrappers for GTSAM. Please refer to the linked documents for more details. | ||||

|     - If the interpreter is inside an environment (such as an anaconda environment or virtualenv environment) then the environment should be active while building gtsam. | ||||
