| Function | Initialization of cartesian-complex numbers |
|
| Syntax C/C++ | #include <VecLib.h>
fComplex fcplx( float ReVal, float ImVal );
(similarly dcplx, ecplx) |
| Pascal/Delphi | uses VecLib;
function fcplx( xRe, xIm: Single ): fComplex;
alternative Syntax (a bit clumsy, but slightly more efficient):
procedure fcplx( var zy:fComplex; xRe, xIm: Single );
(similarly dcplx, ecplx) |

| Description | These functions allow to generate complex numbers of the three cartesian data types fComplex, dComplex, and eComplex. CMATH offers overloaded versions of these functions for C++. See CMATH.HTM, chapter 2.1 for details.
fcplx may be used whenever temporary complex variables are needed as arguments for functions. In this case, fcplx replaces the less elegant direct assignment of the real and imaginary parts, e.g.:
z.Re = 3.0; z.Im = 4.0;
VCF_equC( X, size, z ); /* less convenient */
VCF_equC( Y, size, fcplx( 3.0, 4.0 )); /* easier */
