Dear All, i want to curve-fit a signal in parts/ short intervals and then combine them to obtain the whole signal. I am using NLLS, Levenberg algorithm in curve-fitting toolbox (MATLAB), please guide me

Look into this powerful utility by John D'Errico: SLM: Shape language modeling

Thanks for your reply, i am looing at it.

Hi Daniel, I saw that SLM, that is really a helpful tool for signal smoothing, but the curve fitting i require, gives me some coefficients as a result and i suppose SLM cannot do that.
