Detailed Description

template<unsigned int N, class JResult_t>
struct JTOOLS::JResultPolynome< N, JResult_t >

Data structure for result including value and N derivatives of function.

This data structure contains the following data mambers: 

   JResultPolynome::y[0] = function value;
   JResultPolynome::y[i] = ith derivative; 
   JResultPolynome::y[N] = Nth derivative;

This class implements the JMATH::JMath interface.
