I'm attempting to fit experimental parametric oscillatory data to ellipses and other parametric equations. Would such a task need to be manually coded, or is there a routine already present in IGOR?
I've attached an example plot that I want to fit. oscillator.pxp(57.28 KB)
While I haven't used it myself, I believe support for parametric functions is included in Igor. Try executing DisplayHelpTopic"Fitting Implicit Functions" for more information.

Yes, this is just what I'm looking for. Thank you.
