Does OutputFcn work with linprog?

I am trying to use OutputFcn as follows:

.....................................

history.x = []; history.fval = [];

options=optimset('OutputFcn',
@outfun, 'LargeScale', 'off', 'Simplex', 'on', 'Diagnostics'
, 'on', 'Display', 'iter', 'MaxIter', 10000, 'TolFun', 10e-
8);
[d,fval,exitflag]=linprog(fM,AM,bM,[],[],0,1,[],options);

function stop = outfun (x, optimValues, state)
    stop = false;
    switch state
        case 'iter'
            history.fval = [history.fval; optimValues.fval];
            history.x = [history.x; x];
        otherwise
    end
end

history.fval
history.x

.....................................

But both history.fval and history.x come back empty... am I
missing something?

Thanks!
