Function

Natural cubic-spline interpolation of X-Y-MZ-table values

Syntax C/C++	#include <MFstd.h> void MF_natCubSplineInterpol( fMatrix MZ, fVector X, fVector Y, ui ht, ui len, fVector XTab, fVector YTab, fMatrix MZTab, ui httab, ui lentab );
C++ VecObj	#include <OptiVec.h> void matrix<T>::natCubSplineInterpol( const vector<T>& X, const vector<T>& Y, const vector<T>& XTab, const vector<T>& YTab, const matrix<T>& MZTab );
Pascal/Delphi	uses VFstd; procedure MF_natCubSplineInterpol( MZ:fMatrix; X, Y:fVector; ht, len:UIntSize; XTab, YTab:fVector; MZTab:fMatrix; httab, lentab:UIntSize );

Description

For each of the ht * len x / y coordinates defined by X and Y, the corresponding element of MZ is interpolated from the XTab-YTab-MZTab values. XTab and YTab must be ordered (either ascending or descending). All values of XTab as well as of YTab 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.

Error handling

none (you have to take care yourself that the XTab and YTab values are distinct and that the MZTab values are not near the limit of overflowing).

Return value

none
