Double integral using integral2, too many input arguments

This is the code:

for Y=0:0.01:N,
    eta(round(1+Y*100))=((i*alpha*lambda)^(1/3))*Y+eta0;
    V2(round(1+Y*100))=((i*alpha*lambda)^(-2/3))*q*integral2(@(n) airy(n),eta0,eta,eta0,eta);
end

What's going on?

Error using profiles>@(n)airy(n)
Too many input arguments.

Integral2 assumes the function must have TWO variables. After all, there are TWO integrals being done here. Now read the error message:

Error using profiles>@(n)airy(n)
Too many input arguments.

The function airy that you pass in only has ONE input argument, correct?

Part of me wonders if you are just trying to integrate that function twice. If that is true, then you have chosen the wrong tool, since integral2 is NOT designed to solve that problem.

Thank you! That is exactly what I want to do.

How could I then do?
