Hi folks, I've noticed that MatSetValues explicitly inserts zeros in the matrix if an element is really zero. Is there a way to drop elements (or not save them in the first place) that are below a certain tolerance? I realize one way of doing it is in the application code and when using MatSetValues but I'm just wondering if PETSc has a function for it?
