  File : cimgmatlab_cannyderiche.m

  Description: Example for the CImg plugin: cimgmatlab.h
  which allows to use CImg in order to develop matlab external
  functions (mex functions).
  User should be familiar with Matlab C/C++ mex function concepts,
  as this file is by no way a mex programming tutorial.

  This simple example implements a mex function that can be called 
  as 

  - v = cimgmatlab_cannyderiche(u,s)
  - v = cimgmatlab_cannyderiche(u,sx,sy)
  - v = cimgmatlab_cannyderiche(u,sx,sy,sz)

  The corresponding m-file is cimgmatlab_cannyderiche.m

  for the compilation: using the mex utility provided with matlab, just 
  remember to add the -I flags with paths to CImg.h and/or cimgmatlab.h.
  The default lcc cannot be used, it is a C compiler and not a C++ one!
