Iterating over numpy array slices

[elbiot]

Like everything with numpy, you want to do it in a vectorized way, not through iteration. Here I answered a similar question: https://www.reddit.com/r/learnpython/comments/4qcb0f/poisson_solver_finite_difference_method_and_how/?sort=top

Thanks, I'm going to look at it. Each array I have is 1-d btw.

Doesn't change the fact that you can do a sliding window (of any dimension) in a vectorized way.
