To add or subtract, go entry by entry. The below program multiplies two square matrices of size 4 * 4. Let’s say 2 matrices of 3×3 have elements a[i, j] and b[i, j] respectively.

In Matrix Mode, The Product Block Can Invert A Single Square Matrix, Or Multiply And Divide Any Number Of Matrices That Have Dimensions For Which The Result Is Mathematically.

By multiplying every 2 rows of matrix a by every 2 columns of matrix b, we get to 2x2 matrix of resultant matrix ab. Then multiply the elements of the individual row of the first matrix by the elements of all columns in the second matrix and add the products and arrange the added products in the. Bill shillito shows us how to work with matrices, with tips for adding, subtracting and multiplying (but not dividing!).
