Detailed Description

Class that extends gsl_multiroot_function_fdf so that it can be constructed from arbitrary function objects.

Since gsl::multiroot::function_fdf is a subclass of gsl_multiroot_function_fdf, a pointer to an object of this class can be used whenever a pointer to a gsl_multiroot_function_fdf object is required. Thus, pointers to objects of this class can be used directly with the GNU Scientific Library.

A multiroot::function_fdf with argument a vector of length n should compute and return n function values. In C++ it is straightforward to set up a class with a member function that implements multiroot::function_fdf::Concept to get a suitable function object. The multiroot::function_fdf can then be constructed from a function object of this class.

Constructor & Destructor Documentation

◆ function_fdf() [1/6]

gsl::multiroot::function_fdf::function_fdf ( )

inline

The default constructor is only really useful for assigning to.

Definition at line 425 of file multiroot_function_fdf.hpp.

References count, gsl::multifit::nlinear::df(), func, and gsl::rstat::n().

◆ function_fdf() [2/6]

gsl::multiroot::function_fdf::function_fdf ( gsl_multiroot_function_fdf & v )

inlineexplicit

Could construct from a gsl_multiroot_function_fdf.

This constructor is not actually visible, but gsl::multiroot::function_fdf<T>() will construct the object correctly.

Parameters

v	The gsl_multiroot_function_fdf.

◆ function_fdf() [3/6]

template<typename T >

gsl::multiroot::function_fdf::function_fdf ( T & t )

inline

Construct from an object that implements gsl::multiroot::function_fdf::Concept.

Parameters

t	An object that implements gsl::multiroot::function_fdf::Concept.

Definition at line 460 of file multiroot_function_fdf.hpp.

◆ function_fdf() [4/6]

gsl::multiroot::function_fdf::function_fdf	(	int(*)(gsl::vector const &, gsl::vector &)	f,
		int(*)(gsl::vector const &, gsl::matrix &)	df,
		int(*)(gsl::vector const &, gsl::vector &, gsl::matrix &)	fdf,
		size_t	n
	)

inline

Construct from a function with no parameters (but with n function values and arguments).

Parameters

f	The function to construct from.
df	The derivatives to construct from.
fdf	The function and derivatives to construct from.
n	The number of functions and number of arguments of each.

Definition at line 468 of file multiroot_function_fdf.hpp.

References count, gsl::multifit::nlinear::df(), func, and gsl::rstat::n().

◆ function_fdf() [5/6]

gsl::multiroot::function_fdf::function_fdf ( function_fdf const & v )

inline

The copy constructor.

This shares f. This constructor is not actually visible, but gsl::multiroot::function_fdf::multiroot::function_fdf<T>() will construct the object correctly.

Parameters
