In matlab, fmin* functions accept an extra parameters to the functions
   fminbnd(@(x,a,b) sin(x+a+b),2,6,struct(),1,-2) 
(This is undocumented in current releases, but has been accepted for a long
time)

In order to support this in octave, we need the following patch:

:share/octave/9.1.0/m/optimization$ diff fminbnd.m fminbnd-old.m 
91c91
< function [x, fval, info, output] = fminbnd (fcn, a, b, options = struct (),
varargin = {})
---
> function [x, fval, info, output] = fminbnd (fcn, a, b, options = struct ())
123c123
<     fcn = @(x) guarded_eval (fcn, x, varargin{:});
---
>     fcn = @(x) guarded_eval (fcn, x);
135c135
<   fv = fw = fval = fcn (x, varargin{:});
---
>   fv = fw = fval = fcn (x);
202c202
<     fu = fcn (u, varargin{:});
---
>     fu = fcn (u);
