Sub-package for objects used in interpolation.
|

|
|
|

|
|
As listed below, this sub-package contains spline functions and classes,
|
||
|
|
1-D and multidimensional (univariate and multivariate)
|
||
|
|
interpolation classes, Lagrange and Taylor polynomial interpolators, and
|
||
|
|
wrappers for `FITPACK <http://www.netlib.org/dierckx/>`__
|
||
|
|
and DFITPACK functions.
