Hello
# With regards to my question earlier function f(x) is a vector.
Which is a vector? f(x) or x?

I have a downhill simplex (not a "simplex" in the sense of your
optimization problem). (http://anonimo.isr.ist.utl.pt/ÂŠÃ¾etienne/octave)
Also, a Levenberg-Marquardt-like optimization function, not yet on
my home page. Would you be interested?
Cheers,
Etienne
