Detailed Description

template<class JElement_t, template< class, class > class JCollection_t, class JDistance_t>
class JTOOLS::JHermiteSplineCollection< JElement_t, JCollection_t, JDistance_t >

Template base class spline interpolations.

This class implements the JFunctional interface.

Note that the data structure of the elements in the collection should have the additional methods:

    ordinate_type getU() const;
    void setU(ordinate_type u);

to get and set the derivatives, respectively.

Note that -by default- the compilation is for a monotonous interpolation.
