all target field values, whose source points are not masked by the fractional mask, that receive a interpolation value, which is not a fixed value will by scaled by the following formula:
y = scaling_factor * x + scaling_summand

		struct remote_points *	tgts,
		size_t *	num_stencils_per_tgt,
		size_t *	stencil_indices,
		int *	stencil_ranks,
		double *	w
	)

adds targets whose stencil is the weighted sum of the copies of existing stencils

Parameters

[in]	weights	interpolation weights
[in]	tgts	targets that get the weightes sum
[in]	num_stencils_per_tgt	number of stencils per target
[in]	stencil_indices	indices of the stencils to be copied
[in]	stencil_ranks	ranks of the processs owning the respective stencil
[in]	w	weights

Remarks

this call is collective

yac_interp_weights_write_to_file()

		char const *	filename,
		char const *	src_grid_name,
		char const *	tgt_grid_name,
		size_t	src_grid_size,
		size_t	tgt_grid_size
	)

writes interpolation weights to file

Parameters

[in]	weights	interpolation weights
[in]	filename	file name
[in]	src_grid_name	name of the source grid
[in]	tgt_grid_name	name of the target grid
[in]	src_grid_size	global size of the source grid
[in]	tgt_grid_size	global size of the target grid

Remarks

this call is collective

Global grid size argument can be either the global grid size or zero. If a valid global grid size was provided by at least one process, it will be added as a dimension to the weight file.
