Multiply 1x3 matrix by 3x1

Web3×3 Matrix Multiplication To understand the multiplication of two 3 × 3 matrices, let us consider two 3 × 3 matrices A and B. A = [ 12 8 4 3 17 14 9 8 10], B = [ 5 19 3 6 15 9 7 8 16] Each element of the Product matrix AB can be calculated as follows: AB 11 = 12×5 + 8×6 + 4×7 = 136 AB 12 = 12×19 + 8×15 + 4×8 = 380 AB 13 = 12×3 + 8×9+4×16 = 172 WebMultiplication of a (3x1) with a (1x3) matrix should give a (3x3) matrix.
