Matrix Multiplication Calculator
https://matrix.reshish.com/multiplication.phpMatrix Multiplication Calculator. Here you can perform matrix multiplication with complex numbers online for free. However matrices can be not only two-dimensional, but also one-dimensional (vectors), so that you can multiply vectors, vector by matrix and vice versa. After calculation you can multiply the result by another matrix right there!

https://www.calculator.net/matrix-calculator.htmlMatrix-matrix multiplication: Multiplying two (or more) matrices is more involved than multiplying by a scalar. In order to multiply two matrices, the number of columns in the first matrix must match the number of rows in the second matrix. For example, you can multiply a 2 × 3 matrix by a 3 × 4 matrix, but not a 2 × 3 matrix by a 4 × 3.

Matrices, transposes, and inverses
https://www.math.hmc.edu/~dk/math40/math40-lect07.pdf01.02.2012 · Matrix multiplication not commutative In general, AB = BA. Problems with hoping AB and BA are equal: • BA may not be well-defined. • Even if AB and BA are both defined, BA may not be the same size. • Even if AB and BA are both defined and of the same size, they still may not be equal. (e.g., A is 2 x 3 matrix, B is 3 x 5 matrix) (e.g., A is 2 x 3 matrix, B is 3 x 2 matrix)
