# multiply(Tmatrix4_extended,Tvector4_extended):Tvector4_extended

Give product of a four-dimendional extended precision matrix and vector

## Declaration

Source position: matrix.pp line 580

## Description

This operator allows you to multipy a four-dimensional extended precision matrices with a four dimensional extended precision vector. A new vector is returned which is the product of the matrix and the vector. The product is calculated using the well known matrix-vector multiplication algorithm.
