int find_weighted_hull_average
(
	const Hull *hp,
	double (*weight_fn)(const Vector *),
	Vector **average_vpp
);

DESCRIPTION

This routine finds the point describing the average of the input hull weighted by a user supplied call back function. The first argument "hp" is the address of the convex hull to compute the average of. The second argument is a user supplied function to compute the weighting of a point from a vector of its coordinates. The third argument "average_vpp" contains the address of a vector to become thecomputed hull average. Currently hulls averages are computed using a discrete approximation. The resolution of the descrete space is user settable with the "hir" option, provided that the KJB library options are made available to the user (recommended!).

RETURNS

NO_ERROR on success: ERROR on failure.
