[SciPy-user] documentation on scipy.interpolate

[Timmie]

Hello,
is there a documentation on the interpolation functions included within scipy?

I am particular interested in the kinds of interpolation available in
http://www.scipy.org/doc/api_docs/SciPy.interpolate.interpolate.interp1d.html

The same functionality is used by the timeseries scikit:
http://pytseries.sourceforge.net/lib/interpolation.html#scikits.timeseries.lib.interpolate.interp_masked1d

What does cubic, quintic mean?

Kind regards,
