The example below gave an unexpected error.   

>> fun = @(x) x^2;
>> x = fmincon(fun, x0=0)

In Octave 5.2.0 and optim 1.6.0, I got the right result: 
x = 0

In Octave 7.1.0 and optim  1.6.1, I had an error from the same example.  

error: @<anonymous>: function called with too many inputs
error: called from
    @<anonymous>
    __dfdp__ at line 304 column 15
    fmincon>@<anonymous> at line 385 column 26
    __jacobian_constants__>@<anonymous> at line 135 column 11
    __lm_feasible__ at line 145 column 8
    fmincon at line 451 column 24

Thanks,
