For my application I'm fitting a gaussian curve y(x) = a0 + a1*x + a2*exp(- ((x-a3)/a4)^2) to my measurement data (appr. 200-1000points). In order to optimize the speed of the fitting procedure in C#, I would like to apply and test the different non-linear fitting procedures. Of special interest are the the Levenberg-Marquardt or the Dog-Leg non-linear fitting procedure as present in LabVIEW http://zone.ni.com/reference/en-XX/help/371361D-01/gmath/con_nonlin_curve_fit/
Unfortunately I was not able to find the equivalent in MeasurementStudio Enterprise up to now. Is there an equivalent in MS or are there some demos?
