Re: [Algorithms] Curve fitting problem

[Juan L. <re...@gm...>]

My suggestion may feel hackish but i think it gets the closest to what you
may need.
Just use a cubic spline between the points you want to pass by for sure, and
ignore the others.
Use a second cubic spline that goes through ALL the points.

Interpolate both to the measure you want, and you should have a curve that
passes by some points and gets close to the others.
