alibProd

alibProd

Returns the product of the elements in an array. The PV-WAVE API for this routine is the PRODUCT Function.

Prototypes

wvlong alibProdb( wvlong n, UCHAR *b )

wvlong alibProds( wvlong n, short *b )

wvlong alibProdi( wvlong n, int *b )

wvlong alibProdl( wvlong n, wvlong *b )

double alibProdf( wvlong n, float *b )

double alibProdd( wvlong n, double *b )

COMPLEX alibProdc( wvlong n, COMPLEX *b )

DCOMPLEX alibProdz( wvlong n, DCOMPLEX *b )

Parameters

n — (Input) The number of elements in the source array.

*b — (Input) The n-element source array.

Return value

The product of the elements in array b. Computation is done in the data-type of the return value.

Example

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

#include "alib.h"

void main() {

    /* make up some data for the example */

        UCHAR  b0[5]={1,2,3,4,5};

        wvlong b;

    printf( "\n\n show 5-element vector b0" );

        alibinit( NULL, NULL, NULL, NULL );

        alibPrintArrayb( 1, 1, 1, 5, b0, NULL );

    printf( "\n\n print the product of the elements in b0" );

        b = alibProdb( 5, b0 );

        alibPrintArrayl( 1, 1, 1, 1, &b, NULL );

Output:

 show 5-element vector b0

   1   2   3   4   5

 print the product of the elements in b0
