How do i solve minimax optimization problem?

certain examples are given in help. But when i try the same, its showing error. Can anyone, with an example, be able to explain solving Minimax optimization problem.

Why don't you include the code you tried and the error message in your question?

[Sargondjani]

do you have the optimization toolbox?

you can type 'ver' to see what toolboxes you have

[Sargondjani]

no you dont have the optimization toolbox

function b = three_var(v)

x = v(1);

y = v(2);

z = v(3);

b = x.^2 + 2.5*sin(y) - z^2*x^2*y^2;

v = [-0.6 -1.2 0.135];

a = fminsearch(@three_var,v)

Error using three_var (line 2)

Not enough input arguments. This was the message that i am getting even if try with fminsearch.. kindly elobrate on fminsearch to solve minnimax.. thanks

to solve a minimax program you will have to rely on 'fminsearch', file exchange or write you own optimization routine (this might be less difficult than you think)

Thank you for help.. If u could elobrate on using fminsearch for solving minimax, it will be highly helpful.
