hello,
I've noticed that Octave includes the Powell's hybrid method from
MINPACK for its fsolve function. Since MINPACK also features
nonlinear least squares (via trust-region approach), I suggest
including also that relevant part of MINPACK (lmder,lmdif etc) and
wrap it in a counterpart to fsolve (with similar interface) to do
nonlinear least squares. I'd volunteer for the project.
What do you think?
I'm all for that. I'd like to have more optimization options in
Octave.
Any chance minpack includes a minimax method as well?
Ben
There is an existing nonlinear least squares function (and other
optimization functions) in the octave-forge package "optim". I don't
know how it compares to the MINPACK routine.
