Hi Bob,

I'm not quite sure what you're looking for (esp. the second question), but
maybe something like the following?

#~~~ example code
import numpy as np

nonsquare = np.random.random(size=(3, 5))

M, N = nonsquare.shape
width = max(M, N)
square = np.zeros((width, width))
square[:M, :N] = nonsquare

min_rows = np.min(nonsquare, axis=1)
#~~~
