Hello, I have a function as this:
function l=L2(u1, u2, w, x) l = -sum(log(((log(u1).*log(u2)).^(-1+x)).*((w.^((2-2*x)/x))-(1-x.*(w.^(1-2*x)/2)))./(u1.*u2.*exp(w.^(1/x))))); end
which u1, u2, w are 40*1 vectors, and I want to optimize this for min of x with optimtool but his gives me the error of
Error in the following problem input(s): objective: Not enough input arguments.
Can anybody help me?

Show more code, in particular, the solver that you're using and the code you use to call it.
Also, use markup to make the code you post more readable, including the code in your Question.

Your question might be about how to include extra parameters. See this link.

u1 = ...
u2 = ...
w = ...
objfun = @(x) L2(u1,u2,w,x) % define a function of x with u1, u2, w fixed
Now use objfun as your objective function.
