| CUDA function Pascal/Delphi | uses VFstd;
function cudaVF_splineinterpol( d_Y, d_X:fVector; sizex:UIntSize; d_XTab, d_YTab, d_Y2Tab:fVector; sizetab:UIntSize );
procedure VFcu_splineinterpol( h_Y, h_X:fVector; sizex:UIntSize; h_XTab, h_YTab, h_Y2Tab:fVector; sizetab:UIntSize );

|
| Description | For each of the sizex elements of X, the corresponding element of Y is interpolated from the XTab-YTab value pairs. A table of second derivatives of YTab is needed that has to be generated by a call to VF_splinederiv2 prior to calling VF_splineinterpol. XTab must be ordered (either ascending or descending). All values of XTab must be distinct; otherwise a division by zero may occur and lead to a program abort. sizetab must be greater than or equal to 3.
For a simplified alternative to this function, consider VF_natCubSplineInterpol. |
|
| Error handling | none (you have to take care yourself that the XTab values are distinct and that the YTab values are not near the limit of overflowing). |
