A = [0.60 0.80 1.00 1.00; -0.50 1.00 -0.20 0.90; -0.70 -0.10 1.00 -0.50];
B = [-0.80 -0.70 0.50; -0.10 -1.00 0.00; 0.20 -0.60 -0.40; 1.00 0.60 0.10];

from sympy import *

A = Matrix([[0.60, 0.80, 1.00, 1.00], [-0.50, 1.00, -0.20, 0.90], [-0.70, -0.10, 1.00, -0.50]])
B = Matrix([[-0.80, -0.70, 0.50], [-0.10, -1.00, 0.00], [0.20, -0.60, -0.40], [1.00, 0.60, 0.10]])

Find the product of these two matrices:

Correct answer

$AB=$ [0.640 -1.22 -0.0000000000000000278; 1.16 0.01000 -0.0800; 0.270 -0.310 -0.800]

$AB=$ [[0.640, -1.22, -0.0000000000000000278], [1.16, 0.01000, -0.0800], [0.270, -0.310, -0.800]]
