| Description | simple versions: Yi = sinc( Xi ) = sin( Xi ) / Xi
expanded versions: Yi = C * sinc( A*Xi+B )
The sinc function for an argument of 0.0 is defined as 1.0. The sinc function is the Fourier transform of a square pulse and is used, for example, to describe the diffraction pattern of a slit. |

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