alibIndex

alibIndex

Fills an array with some sequence of evenly spaced numbers. The PV-WAVE API's for this routine are the LINSPACE Function and the *INDGEN routines.

Prototypes

void alibIndexb( wvlong n, UCHAR s, UCHAR i, UCHAR *p )

void alibIndexs( wvlong n, short s, short i, short *p )

void alibIndexi( wvlong n, int s, int i, int *p )

void alibIndexl( wvlong n, wvlong s, wvlong i, wvlong *p )

void alibIndexf( wvlong n, float s, float i, float *p )

void alibIndexd( wvlong n, double s, double i, double *p )

void alibIndexc( wvlong n, COMPLEX s, COMPLEX i, COMPLEX *p )

void alibIndexz( wvlong n, DCOMPLEX s, DCOMPLEX i, DCOMPLEX *p )

Parameters

n — (Input) The number of elements in the array to be populated.

s — (Input) The start value for the sequence of evenly spaced numbers.

i — (Input) The increment for the sequence of evenly spaced numbers.

*p — (Input/Output) The array to be populated. On return, p contains the sequence of n evenly spaced numbers starting with s and incremented by i.

Example

Here we make and print a 9-element array starting with 2 and incremented by 3.

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

#include "alib.h"

void main() {

    wvlong n = 9;

    UCHAR    *b;

    b = (UCHAR*)malloc(n*sizeof(UCHAR));

    alibinit( NULL, NULL, NULL, NULL );

    alibIndexb( n, 2, 3, b );

    alibPrintArrayb( 1, 1, 1, n, b, NULL );

Output:

   2   5   8  11  14  17  20  23  26
