Numpy Play with Rows and Columns of a Matix

[quest]

Don't PM. This all works better when everyone can participate.

Was the problem with transpose that m and m.T reference the same array? If that is a problem, use copy().

import numpy as np

m = []
rows = 64
cols = 64
for r in range(rows):
    m.append([r*cols+c for c in range(cols)])

m = np.array(m)
mT = m.T.copy()  # Get a copy
mT[1][1] = 0
print(mT - m.T)

Hello
Thanks for the answer but the problem is that I cannot bring together 64*1 matrices for creating 64*64 matrix. And I have 64*1 matrices but when I add these 64*1 matrices they are becoming 1*64 matrices and this is very weird By the way I already pasted my code. I didnt understand your example.
