# wnmmlt(3)

vector/matrix multiplication

## NAME

wn\_mult\_mat\_by\_vect, wn\_mult\_mats - vector/matrix multiplication

## SYNOPSIS

```
#include <wn/wnmat.h>

wn_mult_mat_by_vect(double *result_vect,double **mat,double *vect,
int len_i,int len_j)

wn_mult_mats(double **result_mat,double **mat1,double **mat2,
int len_i,int len_j,int len_k)
```

## DESCRIPTION

Vector/matrix multiplication routines.

## RESOURCES

Matrix times matrix requires

WORST and AVERAGE CASE:

time = *len\_i* \* *len\_j* \* *len\_k*\
 stack memory = 1\
 dynamic memory = *len\_j*
