| CUDA function Pascal/Delphi | uses VFmath;
function cudaVF_Lorentz( d_Y, d_X:fVector; size:UIntSize; Wid, Cent, C:Single ): IntBool;
function cusdVF_Lorentz( d_Y, d_X:fVector; size:UIntSize; d_Wid, d_Cent, d_C:PSingle ): IntBool;

| Description | Yi = C * Wid2 / ( (Xi - Cent)2 + Wid2 )
Wid = width of the resonance line
Cent = centre of the line
C is a scaling factor; at the center of the line (Xi=Cent), the amplitude Yi equals C. This is even true for a width of zero. |

| Error handling | This function should be error-proof. |
|
| Return value | always FALSE (0) |
