New Revision: 13719

Added:
   mlpack/trunk/CMake/ModifyMatlabPathdef.cmake
Log:
Script to modify the file which controls the MATLAB default path to add the
"MLPACK toolbox", as I am calling it.  Also in reference to an earlier commit
message, to clarify, my cat is quite seriously weapons-grade stupid.


Added: mlpack/trunk/CMake/ModifyMatlabPathdef.cmake
