How do I clear a temporary PTR Struct in FORTRAN called my Matlab

I have a Matlab file that is calling a mexed FORTRAN routine.... I need to clear out the temporary structures before it returns to Matlab.

Here is how I am creating the temp structure:

mwPointer tmp_strct

tmp_strct = mxCreateStructureMatrix(m,n,fieldnames)

THen I use it with the mxSetFieldByName and mxDuplicateArray functions to load the outputs of plhs. It works fine.......... However, the reason I ask is because i think its retaining memory....ie.... memory leak. :-(

I sometimes get a low memory window pop-up. I am using Matlab 2012b and intel compiler on Windows. Can this tmp_strct be cleared BEFORE returning to matlab.

Can I aleviate this problem ??

Rick - try using mxDestroyArray to free the memory allocated by the mxCreateStructureMatrix function.

Will do.. Thank you
