alibFloat
Converts an array to type
float. This returns the real part of complex input. The PV-WAVE API for this routine is the
FLOAT Function.
Prototypes
void alibFloatb( wvlong n, UCHAR *p, float *r )
void alibFloats( wvlong n, short *p, float *r )
void alibFloati( wvlong n, int *p, float *r )
void alibFloatl( wvlong n, wvlong *p, float *r )
void alibFloatf( wvlong n, float *p, float *r )
void alibFloatd( wvlong n, double *p, float *r )
void alibFloatc( wvlong n, COMPLEX *p, float *r )
void alibFloatz( wvlong n, DCOMPLEX *p, float *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, r is the array obtained from array p by converting each of its elements to type float. If array p is complex then array r is the real part of p.
Example
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include "alib.h"
void main() { UCHAR b0[9] = {0,1,2,3,4,5,6,7,8}; DCOMPLEX z0[9] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17}; float *b;
float *z;
b = (float*)malloc(9*sizeof(float));
z = (float*)malloc(9*sizeof(float));
alibinit( NULL, NULL, NULL, NULL );
printf( "\n\n print the input arrays" );
alibPrintArrayb( 1, 1, 3, 3, b0, NULL );
alibPrintArrayz( 1, 1, 3, 3, z0, NULL );
alibFloatb( 9, b0, b );
alibFloatz( 9, z0, z );
printf( "\n\n print the result arrays" );
alibPrintArrayf( 1, 1, 3, 3, b, NULL );
alibPrintArrayf( 1, 1, 3, 3, z, NULL );
}
Output:
print the input arrays
0 1 2
3 4 5
6 7 8
