Details:

I tried the code from the documentation (23.3 Functions of Multiple
Variables): 

function q = g(y)
  q = ones (size (y));
  for i = 1:length (y)
    f = @(x) sin (pi*x.*y(i)) .* sqrt (x.*y(i));
    q(i) = quadgk (f, 0, 1);
  endfor
endfunction

I = quadgk ("g", 0, 1)

(since I need an integral like Int exp( Int F(x,y) dx) dy) 
I get no result but 100% CPU-load for a very long time.
