alibSinh

Returns the hyperbolic sine of each element in an array. The PV-WAVE API for this routine is the SINH Function.

Prototypes

void alibSinhf( wvlong n, float *p, float *r )

void alibSinhd( wvlong n, double *p, double *r )

void alibSinhc( wvlong n, COMPLEX *p, COMPLEX *r )

void alibSinhz( wvlong n, DCOMPLEX *p, DCOMPLEX *r )

Parameters

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

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

*r — (Input/Output) The n-element destination array. On return, array r contains the hyperbolic sine of each element in array p. The operation can be done in-place, i.e., r can equal p.

Example

#include <stdio.h>

#include <stdlib.h>

#include <math.h>

#include "alib.h"

void main() {

   /* make up some input data for the examples */

   float    f0[4]={1,2,3,4};

   /* make an output array */

   float    f[4];

   printf( "\n\n show 4-element vector f0" );

      alibinit( NULL, NULL, NULL, NULL );

      alibPrintArrayf( 1, 1, 1, 4, f0, NULL );

   printf( "\n\n show the hyperbolic sine of each element in f0" );

      alibSinhf( 4, f0, f );

      alibPrintArrayf( 1, 1, 1, 4, f, NULL );

   printf( "\n\n repeat the operation in-place;  print result as a matrix" );

      alibSinhf( 4, f0, f0 );

      alibPrintArrayf( 1, 1, 2, 2, f0, NULL );

Output:

 show 4-element vector f0

   1.000e+00   2.000e+00   3.000e+00   4.000e+00

 show the hyperbolic sine of each element in f0

   1.175e+00   3.627e+00   1.002e+01   2.729e+01

 repeat the operation in-place;  print result as a matrix

   1.175e+00   3.627e+00

   1.002e+01   2.729e+01
