Hello petsc friends, I have a (silly?) question about matDestroy in Fortran, cause I am not sure I have got 100% clear what it is doing.
I am asking this question because I have the feeling that matDestroy(A, ierr) is not returning the memory to the system, but it prevents from memory leaks. Is that right? If the answer is yes, how can I force petsc to return all the memory used for A to the system? I found this post: https://lists.mcs.anl.gov/pipermail/petsc-users/2013-August/018466.html, but cannot use that trick as I am not in C here. Thanks for the help as always!
