file	gcvspl
for	B-spline data smoothing using generalized cross-validation and mean squared prediction or explicit user smoothing
by	H.J. Woltring,  University of Nijmegen, Philips Medical Systems, Eindhoven (The Netherlands)
#	Natural B-spline data smoothing subroutine, using the Generalized Cross-
#	Validation and Mean-Squared Prediction Error Criteria of Craven & Wahba
#	(1979). Alternatively, the amount of smoothing can be given explicitly, or
#	it can be based on the effective number of degrees of freedom in the
#	smoothing process as defined by Wahba (1980). The model assumes
#	uncorrelated, additive noise and essentially smooth, underlying functions.
#	The noise may be non-stationary, and the independent co-ordinates may be
#	spaced non-equidistantly. Multiple datasets, with common independent
#	variables and weight factors are accomodated.  A full description of the
#	package is provided in:  H.J. Woltring (1986), A FORTRAN package for
#	generalized, cross-validatory spline smoothing and differentiation.
#	Advances in Engineering Software 8(2):104-113
