FunctionDerivative of one array with respect to another
Syntax C/C++#include <VFstd.h>
void VF_derivV( fVector Z, fVector X, fVector Y, ui size );
C++ VecObj#include <OptiVec.h>
void vector<T>::derivV( const vector<T>& X, const vector<T>& Y );
Pascal/Delphiuses VFstd;
procedure VF_derivV( Z, X, Y:fVector; size:UIntSize );
DescriptionZ(X) = dY(X) / dX.
The derivative of Y with respect to X is calculated by parabolic interpolation and stored in Z. If the elements of X are equally-spaced, it is better to use VF_derivC. The inverse procedure, i.e. integration, is performed by VF_runintegralV.
