15 Jun 2004	Eric Shain	At least 7 times faster than interp1 with the spline option.

22 Jul 2004	Rod Derrick	Impressive accuracy and speed of the osculatory mode SPLIN! Rating 1 below is apparently in European style!
01 Dec 2004	gwang guen kim	so good!
21 Oct 2005	Emre Evren	very fast and seems reliable. cubic with continuous derivatives.. very good.

13 Feb 2008	Georgina Kincaid	No better than the interpolation tools already in matlab. The help looks like it was written by a third grader. Not worth reading the impenetrable help to figure out how to use this to interpolate.
