[Octave-bug-tracker] [bug #61801] [octave forge] (optim) lsqnonlin and fmincon test failures

[Sébastien Villemot]

Follow-up Comment #11, bug #61801 (project octave):

Many problems with Octave 7.1.0 have indeed been fixed in the mercurial
repository.

However, I still experience one (as of 83eefe952baa):


octave:1> pkg load optim
octave:2> function [v, d] = optimf(x)
>   v = x^2;
>   d = 2*x;
> end
octave:3> optim_options = optimset('GradObj','on');
octave:4> fmincon(@optimf, 3, [], [], [], [], 2, 4, [], optim_options)
error: @<anonymous>: function called with too many inputs
error: called from
    fmincon>@<anonymous>
    __jacobian_constants__>@<anonymous> at line 135 column 11
    __lm_feasible__ at line 145 column 8
    fmincon at line 456 column 24


It is apparently triggered by the combination of explicit gradient with
optimization bounds.
