numpy built in to transpose a matrix code example

Example 1: transpose matrix numpy

>>> a = np.array([[1, 2], [3, 4]])
>>> a
array([[1, 2],
       [3, 4]])
>>> a.transpose()
array([[1, 3],
       [2, 4]])
>>> a.transpose((1, 0))
array([[1, 3],
       [2, 4]])
>>> a.transpose(1, 0)
array([[1, 3],
       [2, 4]])

Example 2: transpose matrice numpy

>>> np.transpose(M)
array([[1, 4, 7],
       [2, 5, 8],
       [3, 6, 9]])
