Curve Fitting Software.

Has anyone ever used one? I am using “CurveExpert” and its prettey good except for the fact that it won’t let me enter the “error bars” in the data points… I can see option but its not activated. Btw, its not standard deviation bars, the error bars i need to enter have been obtained externally.

If anyone has persoally used others that work well and allow you to enter error bars, then can you plz let me know, JAK.

Re: Curve Fitting Software.

What are you looking at doing with this: Obtain the polynomial coefficients for the best curve fit or for data interpolation? Just curious...

Re: Curve Fitting Software.

^ yes... well I need it more to fit a linear plot but also a polynomial one....

the option I really need to be able to use is one where you can individually enter the value of error bars on the linear plots (which I am not able to do with this current software)
