Dear Beatriz,

Thanks for your post. I am copying the discussion between you and Sungeun here, in case anyone else has a similar problem. If the LocalSmoothing executable is incompatible with your OS, you need to compile “LocalSmoothing.c” located in “C_sources” directory and copy the mex file to SPHAR-MAT root directory.

The following link contains the information about how to compile “LocalSmoothing.c” on Linux
http://imaging.indyrad.iupui.edu/project...
and it is very easy and you can issue a command on the Matlab command windows:
mex LocalSmoothing.c -lmwlapack -lmwblas

Thanks,

Li
