[Octave-bug-tracker] [bug #63286] [octave forge] (optim) fmincon fails for Rosenbrock example

[Arun Giridhar]

Follow-up Comment #12, bug #63286 (project octave):

I'm not seeing any notice that optim is not being maintained.  Where did you
see it?
https://gnu-octave.github.io/packages/optim/

I recall that fmincon was added only to serve as a Matlab-compatible wrapper
to nonlin_min. If you can live without Matlab function name compatibility, can
you try nonlin_min directly? That is generally more powerful than fmincon. If
that works but fmincon doesn't, then at least we'll have localized the
problem.
