Detailed Description

One-dimensional minimisation.

Function Documentation

find_bracket()

int gsl::min::find_bracket ( function_scl &  f, double &  x_minimum, double &  f_minimum, double &  x_lower, double &  f_lower, double &  x_upper, double &  f_upper, size_t  eval_max  )

inline

C++ version of gsl_min_find_bracket().

Parameters

f	the function to be minimised.
x_minimum	Current estimate of the value that minimises f.
f_minimum	Value of f at x_minimum.
x_lower	Lower bound of the interval containing minimum.
f_lower	Value of f at x_lower.
x_upper	Upper bound of the interval containing minimum.
f_upper	Value of f at x_upper.
eval_max	Maximum number of evaluations.

Returns

GSL_SUCCESS if initial bracketing interval found; otherwise GSL_FAILURE.

test_interval()

int gsl::min::test_interval ( double  x_lower, double  x_upper, double  epsabs, double  epsrel  )

inline

C++ version of gsl_min_test_interval().

Parameters

x_lower	Lower bound of interval containing minimum.
x_upper	Lower bound of interval containing minimum.
epsabs	Absolute error.
epsrel	Relative error.

Returns

GSL_SUCCESS if condition met.
