Linear Algebra Differential Equations Multiplication Matrix Matrix Multiplication. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result. The examples above illustrated how to multiply 22 matrices by hand.

In the above image 19 in the 00 index of the outputted matrix is the dot product of the 1st row of the 1st matrix and the 1st column of the 2nd matrix. 2x3 by 3x2 or QxD by DxW The dimensions of the result will depend on the outer numbers. Rows of the 1st matrix with columns of the 2nd.

Next multiply times the second column and add to get the second number in the first row of the answer. Suppose we also have a 32 matrix B which has 3 rows and 2 columns. Suppose we have a 33 matrix A which has 3 rows and 3 columns.

3x2 2x3 3x3 3x1. The Multiplication of a 2x3 Matrix by a 3x2 Matrix calculator computes the resulting 2x2 matrix C produced by the matrix multiplication of 3x3 matrix A and 3x3 matrix B. We have a nested for loop designed to go through the columns of A and rows of B and add the products of the values in those rows and columns.
