10As listed below, this sub-package contains spline functions and classes, 

111-D and multidimensional (univariate and multivariate) 

12interpolation classes, Lagrange and Taylor polynomial interpolators, and 

13wrappers for `FITPACK <http://www.netlib.org/dierckx/>`__ 

14and DFITPACK functions.
