fmincon (optimization toolbox) - bug?

hi, does anyone have experience with fmincon? it seems that
no matter what I do, I get the message
Warning: Large-scale (trust region) method does not
currently solve this type of problem,
using medium-scale (line search) instead.
> In fmincon at 317
so, I look in line 317. I find
elseif ~line_search
[error-message]
but linesearch is defined as
line_search = strcmp(optimget
(options,'LargeScale',defaultopt,'fast'),'off')
, with the explanatory note
% line_search = false means large scale (trust region),
line_search = 1 means medium scale (line search)
So, am I correct in deducing that this program will abort
large-scale when told to use it, and won't when told not to
use it? is it possible that I have located an error?
cheers, hope someone out there has a suggestion
