Re: Curve Fitting

There is such a function that was contributed by a user to the Matlab ftp
site.  It's in and it's
called curvefit.m.  This fit's straight lines and plots them with the
data.  There is also curvefitnl.m which proports to do the same for a
user-specified non-linear function but I haven't tried it.

If you want to abstract from any particular functional form then I wrote a
function which does kernel smoothing which I could give you.  It fit's the
best curve to 2-dimensional data without any need to specify the
functional form. If you are interested let me know.
