Spline Tools
===================
This package contains wrappers around the netlib Dierckx library for curve
and surface fitting with splines.
Two interfaces are provided. The prefered interface is an object orientated
interface defined in spline.spline:
UnivariateSpline -- 1 dimensional, smoothing or interpolating spline
InterpolatedUnivariateSpline -- i dimensional interpolating spline
LSQUnivariateSpline -- 1 dimensional least squares fitted spline
SmoothBivariateSpline -- 2 dimensional smoothing spline on scattered data
LSQBivariateSpline -- a least scquares fitted spline for scattered data
RectBivariateSpline -- a 2 dimensional smoothing or interpolating spline
on regular gridded rectangular data
An alternative interface is a more direct wrapping of the fortran rountines:
splrep -- find smoothing spline given (x,y) points on curve.
splprep -- find smoothing spline given parametrically defined curve.
splev -- evaluate the spline or its derivatives.
splint -- compute definite integral of a spline.
sproot -- find the roots of a cubic spline.
spalde -- compute all derivatives of a spline at given points.
bisplrep -- find bivariate smoothing spline representation.
bisplev -- evaluate bivariate smoothing spline.
