"""
Given a matrix and a target, return the number of non-empty sub matrices that sum to target.
A sub matrix x1, y1, x2, y2 is the set of all cells matrix[x][y] with x1 <= x <= x2 and y1 <= y <= y2.
Two sub matrices (x1, y1, x2, y2) and (x1', y1', x2', y2') are different if they have some coordinate that is different:
for example, if x1 != x1'
