db_vcloud()

GSTLEARN_EXPORT DbGrid* db_vcloud	(	Db *	db,
		const VarioParam *	varioparam,
		double	lagmax,
		double	varmax,
		int	lagnb,
		int	varnb,

Evaluate the experimental variogram cloud

Returns

Error return code

Parameters

[in]	db	Db descriptor
[in]	varioparam	VarioParam structure
[in]	lagmax	Maximum distance
[in]	varmax	Maximum Variance value (see remarks)
[in]	lagnb	Number of discretization steps along distance axis
[in]	varnb	Number of discretization steps along variance axis
[in]	namconv	Naming convention

Remarks

If 'lagmax' is not provided, it is set to the diagonal of the area covered by the active samples within 'db'.

If 'varmax' is not defined, it is set to 3 times the experimental variance of the first variable (Z_locator)
