I was trying to avoid the loop. I figured it out. hsplit and vsplit will work.
I just need to give it a list of break points. I still need a loop though.
breakPoints = range(49,512,59)
rowArrays = hsplit(InputArray, breakPoints)
OutArrays = []
for r in rowArrays:
OutArrays.append(vsplit(r, breakPoints))
