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
warning: unrecognized escape sequence `\N' -- converting to `N'

BFGSMIN final results

Used numeric gradient

Function conv 1  Param conv 1  Gradient conv 1

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.
