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'.
