[gdal-dev] curve fit question

Does anyone know of a function in GDAL or related libraries that given a
set of points it will return a new set of points that is or can be used
to create a smoothed polyline?  I have heard about things like linear
fit and least squares but I have not used them and I am quite rusty on
the math used to calculate a smoothed line from a set of points.  I have
done a lot of web searching and found various generic algorithms but I
don't see how to apply them.  For example a linear regression sample
takes in a set of X-Y points but it only returns 3 values of C and
standard deviation. 


Any help would be greatly appreciated.
