Function Documentation

cs_array_real_copy()

void cs_array_real_copy	(	cs_lnum_t	n_elts,
		cs_lnum_t	dim,
		const cs_real_t	src[],
		cs_real_t	dest[restrict]
	)

Copy real values from an array to another of the same dimensions.

Parameters

[in]	n_elts	number of associated elements
[in]	dim	associated dimension
[in]	src	source array values (size: n_elts*dim)
[out]	dest	destination array values (size: n_elts*dim)

cs_array_real_copy_sublist()

void cs_array_real_copy_sublist	(	cs_lnum_t	n_elts,
		int	stride,
		const cs_lnum_t	elt_ids[],
		int	mode,
		const cs_real_t	ref[],
		cs_real_t	dest[]
	)

Copy an array ("ref") into another array ("dest") on possibly only a part of the array(s). Array with stride > 1 are assumed to be interlaced. The sublist of element on which working is defined by "elt_ids" (of size "n_elts"). The way to apply the sublist is set with the parameter "mode" as follows:

• Only the "ref" array if mode = 0 (CS_ARRAY_IN_SUBLIST)
• Only the "dest" array if mode = 1 (CS_ARRAY_OUT_SUBLIST)
• Both "ref" and "dest" arrays if mode = 2 (CS_ARRAY_INOUT_SUBLIST)

It elt_ids = NULL or mode < 0 (CS_ARRAY_NO_SUBLIST), then the behavior is as cs_array_real_copy

One assumes that all arrays are allocated with a correct size.

Parameters

[in]	n_elts	number of elements in the array
[in]	stride	number of values for each element
[in]	mode	type of indirection to apply
[in]	elt_ids	sub list of element ids to consider
[in]	ref	reference values to copy
[in,out]	dest	array storing values after applying the indirection

cs_array_real_fill_zero()

void cs_array_real_fill_zero	(	cs_lnum_t	size,
		cs_real_t	a[]
	)

Assign zero to all elements of an array.

Parameters

[in]	size	total number of elements to set to zero
[in,out]	a	array to set

cs_array_real_set_scalar()

void cs_array_real_set_scalar	(	cs_lnum_t	n_elts,
		cs_real_t	ref_val,
		cs_real_t	a[]
	)

Assign a constant scalar value to an array.

Parameters

[in]	n_elts	number of elements
[in]	ref_val	value to assign
[in,out]	a	array to set

cs_array_real_set_scalar_on_subset()

		const cs_lnum_t	elt_ids[],
		cs_real_t	ref_val,
		cs_real_t	a[]
	)

Assign a constant scalar value to an array on a selected subset of elements. If elt_ids = NULL, then one recovers the function cs_array_real_set_scalar.

Parameters

[in]	elt_ids	list of ids defining the subset or NULL
[in]	ref_val	value to assign
