# multiply(Tmatrix2_double,Tvector2_double):Tvector2_double

Give product of a two-dimensional double precision matrix and vector.

## Declaration

Source position: matrix.pp line 575

## Description

This operator allows you to multiply a two-dimensional double precision matrices with a two dimensional double 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.
