Detailed Description

template<class DataPoint, class _WFunctor, int Type, typename T>
class Ponca::PrimitiveDer< DataPoint, _WFunctor, Type, T >

Generic class performing the Fit derivation.

The differentiation can be done automatically in scale and/or space, by combining the enum values FitScaleDer and FitSpaceDer in the template parameter Type.

The differentiated values are stored in static arrays. The size of the arrays is computed with respect to the derivation type (scale and/or space) and the number of the dimension of the ambiant space. By convention, the scale derivatives are stored at index 0 when Type contains at least FitScaleDer. The size of these arrays can be known using derDimension(), and the differentiation type by isScaleDer() and isSpaceDer().
