Repeated Permutation of Powers
Let’s say I have two radix/base values x and y (both are floats, not ints) and I need to quickly generate all combinations of:
How to put a Python numpy array back together from diagonals obtained from splitting the array into right to left diagonals in first place?

The code below works for the 4×3 array, but does not for the 3×5 and the other ones:
