I'm sorry. I can't help you with the actual task. However, the lambda 
above is superfluous. Consider the simple analog


do_stuff(lambda x: f(x))

If you rewrite it with a "normal" function this becomes

def g(x):
     return f(x)

do_stuff(g)

and it should be easy to see that g() wraps f() without doing any extra 
work; so you better write

do_stuff(f)

directly, or in your case

fixed_quad(DEx11, ...)
