I defined the function

function y = myfun2(x,c)
  global p;
  p = 10;
  y = 1./(x.^3-2*x-c);
end

and then did the following in matlab

>> global p
>> p = 5;
>>  Q = quad(@(x)myfun2(x,p),0,2)

Q =

   -0.4605

>> p = 10;
>>  Q = quad(@(x)myfun2(x,p),0,2)

Q =

   -0.2043

>>

I think this makes it pretty clear that the anonymous variable is
evaluated when the anonymous function is declared...
