# Matrix multiplication calculator

### Computes product of two matrices A and B

This operation takes two matrices as input and produces a matrix as output. The number of columns in the A matrix must be the same as number of rows in the B matrix.Numbers contained in the rows of the A matrix are multiplied by matching columns of the B matrix.

For full definition, see Wikipedia.

Enter numbers in the blank fields of matrices A and B. If inputted matrix has less than 3 rows and columns, leave the unneeded row/column blank. If a matrix has more than 3 rows or columns, click the "+column" or "+row" text to add new fields which you can fill with numbers. Maximal number of columns is ten.
