Scalar and Matrix Multiplication

This page will perform online matrix multiplication. You can perform two types of multiplication for matrices: scalar multiplication and matrix multiplication. Scalar multiplication is easy. You just take a regular number (called a “scalar”) and multiply it on every entry in the matrix. With matrix matrix multiplication, you multiply two matrices where the number of columns in matrix A is equal to the number of rows in matrix B. If A is of size (n,m), and B is of size (m,p), you get a new matrix AB with size (n,p)

The online matrix addition page allows you to input two matrices of the same size. The sum is defined by adding entries with the same indices over all the entries of the matrices
