Enter the command ?"%*%" and you will see: Matrix Multiplication Description: Multiplies two matrices, if they are conformable. If one argument is a vector, it will be promoted to either a row or column matrix to make the two arguments conformable. If both are vectors it will return the inner product (as a matrix).
