dyadic_splitting()

template<typename Function , typename Container >

auto CoolProp::superancillary::detail::dyadic_splitting ( const std::size_t  N, const Function &  func, const double  xmin, const double  xmax, const int  M = 3, const double  tol = 1e-12, const int  max_refine_passes = 8, const std::optional< std::function< void(int, const Container &)> > &  callback = std::nullopt  ) -> Container

inline

std::function<double(double)>

get_LU_matrices()

auto CoolProp::superancillary::detail::get_LU_matrices ( std::size_t  N )

inline

Get the L and U matrices needed for transformations between nodes and function values in a Chebyshev expansion.

The L matrix is used to convert from functional values to coefficients, as in

\[ \vec{c} = \mathbf{L}\vec{f} \]

The U matrix is used to convert from coefficients to functional values, as in

\[ \vec{f} = \mathbf{U}\vec{c} \]

Parameters

N	the degree of the expansion (one less than the number of coefficients)

< Matrix of coefficients

< Matrix of coefficients

toms748()

double CoolProp::superancillary::detail::toms748	(	const std::function< double(double)> &	f,
		double	a,
		double	b,
		double	fa,
		double	fb,
		unsigned int	bits,
		std::size_t	max_iter
	)

Bracketing rootfinder (Boost's TOMS 748). Declared here but DEFINED out-of-line in src/superancillary.cpp so the boost dependency stays internal to the compiled CoolProp library – consumers of this installed header do not need boost on their include path. f is the residual function and [a, b] a bracket with fa = f(a), fb = f(b); bits is the TOMS 748 bit tolerance and max_iter the function-call cap. Returns the midpoint of the final bracket.
