Description: Example of use for the CImg plugin 'plugins/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!
