 This is the GTSAM MATLAB toolbox, a MATLAB wrapper around the GTSAM C++
 library. To build it, enable GTSAM_INSTALL_MATLAB_TOOLBOX in CMake.

+The interface to the toolbox is generated automatically by the wrap
+tool which directly parses C++ header files. The tool generates matlab
+proxy objects together with all the native functions for wrapping and
+unwrapping scalar and non scalar types and objects. The interface
+generated by the wrap tool also redirects the standard output stream
+(cout) to matlab's console.
