I plotted data and then fitted it with a curve. Now I want to find a

keeps coming up.
Xdata = 0.1:.001:1.6;
plane = spline(X, Y, Xdata)
If you had a variable named 'spline', or if for some reason the
routine named 'spline' could not be found, then Matlab would think
you were trying to access a variable named 'spline' with
indices that were not integers.
spline() does appear to be a part of basic matlab, at least in
R2007a. I glanced around but could not find any information as
to when it was introduced as an independant function
(as an option to interp1 it goes back to at least Matlab 6.1)
