How to output multiple results via function

Maybe this is a basic question. Please help me with it. I define a function with a couple parameters.

function f=fun(y,lambda)

[y,fval]=fmincon(@(y)fun(y,lambda),y0,[],[],[],[],[],[],[],[])

y is chosen to minimize function fun. The outputs are y and fval. I would like to output some other values, for example, y*lambda. I know I can output y*lambda in the next step after fmincon. How to output y*lambda directly in the function or in optimization problem?

Do you mean from the function fun?

It's pretty easy:

 function [f,yl,otherstuff] =fun(y,lambda) 

[y,fval]=fmincon(@(y)fun(y,lambda),y0,[],[],[],[],[],[],[],[]);
yl = y*lambda;
otherstuff = otherstuff_create();

end

Like this.

Thanks for your prompt response. But it seems that when I ran it it still shows only y and fval, not y1 and otherstuff. Do you have any idea?

You have to store the output as well, or display it. For instance, you would call that function like this:

 [f,yl,otherstuff] = fun(y,lambda)

I'm not sure exactly what your function is, though, so I can't be more precise.
