virtual double evaluate (double x) const =0
 
double get_integral (double xmin, double xmax, unsigned int max_subintervals=1000, double error_limit=1e-7) const
 

Detailed Description

Base class of all function classes which should be integrated. To use this class, derive from it and overload the virtual function 'evaluate'.

Member Function Documentation

§ evaluate()

virtual double Integrand::evaluate ( double  x) const
pure virtual

Returns the function value at position 'x'.

§ get_integral()

double Integrand::get_integral ( double  xmin,
double  xmax,
unsigned int  max_subintervals = 1000,
double  error_limit = 1e-7 
) const

Returns the integral from 'xmin' to 'xmax'. Integration is performed with 'max_subintervals' at which the function will be calculated and the specified relative 'error_limit'.
