In a mel script I'm doing, I require a huge global matrix - sommit like :
global matrix $Some\_Matrix[100][100];
My question is - The matrix obviously takes up a large amount of memory, is there any way to delete it after the script has finished processing? or is it going to float around until Maya quits?
I know you can use clear with arrays, but is there any similar proc for matrices?
Alternatively - is there any way to dynamically allocate memory for a matrix?

Is it possible to have the matrix be local to a procedure instead of global? If so, it will clean itself up when the procedure is done running.

It has to exist for the duration of the script, but the script runs an app, around which the core data is this matrix. I can't see any way of making it local, but at the same time getting rid of it would be nice.
