Find maximum of constrained multivariable function

Hey,

I am looking for maximum optimization of a constrained nonlinear multivariable function. I found some solvers for minimum optimization of constrained nonlinear multivariable function, like fmincon ,fminsearch etc. But I need maximization of the same function.

Thanks- Mahir.

Minimizing -f(x) it is equivalent to maximizing f(x).

[mahir]

so its a simple mathematical thing....no functional trick is required....thanks .....i have one more ques...i am working with optimtool box and the fmincon solver....how do i extract the optimized data in a variable after optimization ends

There is an Export To Workspace dialog
