Re: lsqnonlin?

[Michael Creel]

There's an NLS routine in Octave Forge, econometrics package. It looks like I might need to give it a little attention, though:

octave:1> nls_example

Maybe you should replace the code of lsqnonlin whatever it is, with
calls to the function leasqr() for the LevMar process fits. LevMar
curve fit on leasqr() worked for me.

I have no idea what is lsqnonlin, and I think you probably have the
source code for lsqnonlin.

Hope it helps.
