| Function | Initialization of polar-complex numbers |
|
| Syntax C/C++ | #include <VecLib.h>
fPolar fpolr( float MagVal, float ArgVal );
(similarly dpolr, epolr) |
| Pascal/Delphi | uses VecLib;
function fpolr( xMag, xArg:Single ): fPolar;
alternative Syntax (a bit clumsy, but slightly more efficient):
procedure fpolr( var py:fPolar; xMag, xArg:Single );
(similarly dpolr, epolr) |
|
| Description | These functions allow to generate numbers of the three polar-complex data types fPolar, dPolar, and ePolar. CMATH offers overloaded versions of these functions for C++. See CMATH.HTM, chapter 2.1 for details.
fpolr may be used whenever temporary complex variables are needed as arguments for functions. In this case, fpolr replaces the less elegant direct assignment of the Mag and Arg parts, e.g.:
p.Mag = 3.0; p.Arg = 1.5708;
VPF_equC( X, size, p ); /* less convenient */
VPF_equC( Y, size, fpolr( 3.0, 1.5708 )); /* easier */
