Function Documentation

fvm_hilbert_compare()

int fvm_hilbert_compare	(	const void *	elt1,
		const void *	elt2,
		const void *	input )

Function pointer for comparison of 2 Hilbert codes.

This function is the same type as that used by qsort_r.

Parameters

[in]	elt1	coordinate between 0 and 1
[in]	elt2	pointer to optional (untyped) value or structure.
[in]	input	pointer to optional (untyped) value or structure.

Returns

< 0 if elt1 < elt2, 0 if elt1 == elt2, > 0 if elt1 > elt2

		cs_lnum_t	order[] )

fvm_hilbert_s_to_code()

void fvm_hilbert_s_to_code	(	double	s,
		void *	elt,

Parameters

[in]	s	coordinate between 0 and 1
[out]	elt	pointer to element
[in]	input	pointer to optional (untyped) value or structure.
