Re: Optimisation

  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/Šþetienne/octave) 

  Also, a Levenberg-Marquardt-like optimization function, not yet on
my home page. Would you be interested?

  Cheers,
