cmplxdbl
Returns a double-precision complex number for two real inputs. The PV-WAVE API for this routine is the DCOMPLEX Function.
Prototype
DCOMPLEX cmplxdbl( double r, double i )
Parameters
r — (Input) The real part of the complex number.
i — (Input) The imaginary part of the complex number.
Return value
The double-precision complex number (r,i).
Example
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include "alib.h"
void main() {
    DCOMPLEX z;
    alibinit( NULL, NULL, NULL, NULL );
    z = cmplxdbl( 1, 2 );
    alibPrintArrayz( 1, 1, 1, 1, &z, NULL );
}
 
Output:
 
(    1.0e+00    2.0e+00 )
