Maximization problem in MATLAB Optimisation Toolbox

Basically by default MATLAB OPtimisation Toolbox fminocon and ga algorithms minimise the objective function.
To maximise normally we use duality prinicple i.e., "multiplying objective function by -1". Will it work same here?
Becasue I have tried doing this and I couldnt get proper results. Is there any solution for this?
Thank you in advance!!

Yes. Example:
fun=@(x) -x^2; %maximize this
xmax=fmincon( @(x) -fun(x) , 1)
It worked!!
But another principal is that you need a good initial guess, when the problem is non-convex. That might be why it "doesn't work" for you.
