Element pl-matrix-input: Matrix algebra with complex values

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

A = [-1.00-0.80j 0.90+0.20j; -0.90-0.30j -0.70+0.60j];
B = [0.50+0.50j 0.70-0.20j; -0.50+0.90j 0.90-0.40j];

A = {{-1.00-0.80j, 0.90+0.20j}, {-0.90-0.30j, -0.70+0.60j}};
B = {{0.50+0.50j, 0.70-0.20j}, {-0.50+0.90j, 0.90-0.40j}};

from sympy import *

A = Matrix([[-1.00-0.80j, 0.90+0.20j], [-0.90-0.30j, -0.70+0.60j]])
B = Matrix([[0.50+0.50j, 0.70-0.20j], [-0.50+0.90j, 0.90-0.40j]])

Find the product of these two matrices:

Correct answer

$AB=$ [-0.73-0.19j 0.03-0.54j; -0.49-1.53j -1.08+0.79j]

$AB=$ [[-0.73-0.19j, 0.03-0.54j], [-0.49-1.53j, -1.08+0.79j]]
