C6.32. Matrix input: random parameters and correct answer

Two matrices $A$ and $B$ are given as follows:

Matlab/Octave
NumPy

A = [-1.0 -0.7 0.7 0.4 1.0; -0.2 0.9 0.8 0.2 0.9; 0.3 -0.6 0.3 0.2 -0.7; 0.1 0.9 0.0 0.2 0.2];
B = [0.1 0.1 -0.2 -0.3; 0.8 -0.5 0.1 -0.3; 1.0 0.8 -0.1 -0.7; -1.0 -0.9 0.6 -0.1; -0.7 -0.9 -0.1 -0.8];

import numpy as np

A = np.array([[-1.0, -0.7, 0.7, 0.4, 1.0], [-0.2, 0.9, 0.8, 0.2, 0.9], [0.3, -0.6, 0.3, 0.2, -0.7], [0.1, 0.9, 0.0, 0.2, 0.2]])
B = np.array([[0.1, 0.1, -0.2, -0.3], [0.8, -0.5, 0.1, -0.3], [1.0, 0.8, -0.1, -0.7], [-1.0, -0.9, 0.6, -0.1], [-0.7, -0.9, -0.1, -0.8]])
