cleaning functions in MEX files

Dear all,
I have some issues with MATLAB cleaning functions in MEX files. In the link below is a zip file containing the c++ code, some data to test it and a m file to build it and run it.
I was able to compile it under linux before but from a system upgrade it won't anymore. I narrowed the problem down to the cleaning part when returning to windows but my knowledge in c++ stops here. I didn't wrote the code myself (I adapted it for matlab and the large arrays dim).
Thank you for your help,
Cédric

Hi Cédric,
Have you solved the problem already? If not, can you provide an example you would call mf2 from the Matlab prompt? What exactly did you mean by the "cleaning part"?

This will fail if the input is a DOUBLE array:
float *sourcesinkVal;
sourcesinkVal = (float *) mxGetPr(prhs[0]);
Better use:
float *sourcesinkVal;
if (!mxIsSingle(prhs[0])) {
mexErrMsgTxt("1st input must be a SINGLE.");
}
sourcesinkVal = (float *) mxGetData(prhs[0]);
It is not clear where the function crashs. Please post more details.
