How can I install Optimization toolbox?

function F =fun(x)

    F(1) = exp(-exp(-(x(1)+x(2)))) - x(2)*(1+x(1)^2);
    F(2) = x(1)*cos(x(2)) + x(2)*sin(x(1)) - 0.5;
    
end

command box

>> x0=[0;0];

>> fsolve(@(x) fun(x),x0)

'fsolve' requires Optimization Toolbox.

Why this is happening?

How can I install fsolve?

[Steven Lord]

The fsolve function is part of Optimization Toolbox. You can check if you have this toolbox installed by running the ver command and looking for a line starting with "Optimization Toolbox" in the displayed output.
