We call free() at that point. But not that in Unix this does not

Also note that MatDestroy only releases a references, so if another
object still holds a reference to your matrix, nothing will be freed.
Thank you!
Just to clarify: if a code reads like this:
Mat A;
MatCreate(MPI_COMM_WORLD, &A);
Mat B = A;
....
MatDestroy(&B);
Will the free() function be called for the memory that contains the
matrix data in this case?
Thank you,
Michael.
