Hi!

Last time I got a very helpful idea. Now I defined a vectorfunction which has several variables x1,x2,x3,u1,u2 and also several outputs y1,y2,y3,...,yN. Now I would like to optimize only one output, i.e. I optimize f.ex. only y3. In my case y3 is a function that I get from y1,y2... .

I tried to find the answer, but mostly fminunc were used to optimize y or y1,y2,y3,..... What is the command in the fminunc solver to optimize only one output?

Thanks

在 MATLAB Online 中打开

Inside of your objective function, only return that output:

function y3 = myobjfun(x)
% do whatever
y3 = something;
end

Your efficiency function obviously returns an array. It must be a scalar though. Maybe you actually want to optimize w.r.t. norm(efficiency)?
