The product of the matrices is a 1 x 1 matrix of -9.
A matrix is an array of numbers or expressions used in solving complex problems. Matrices are also used in solving system of equations.
The matrices are
[4 3 -1 -1] [-3 1 -2 2]
The multiplication of the matrices is
c11 = 4 x (-3) + 3 x 1 + (-1) x (-2) + (-1) x 2 = -9
[-9]
