So I have equations:
(a##-d## are all decimals)
And I want to double integrate over d and h. So just for example I can integrate over just d:
and it evaluates just fine. Likewise if I put in an value for d and integrate over h, it also produces a value.
So I want the numerical approximation of this double integral, but when I try for it using:
At any rate, I think what is happening is that it is trying to evaluate the inside integral numerically first perhaps, which it is not able to do as it has a variable?
I tried using the lambda in the first answer, and I was able to evaluate, but I had to set it to max_points=10 to get an answer that was even close to correct, plus I could find no way to plot that one.
Thanks for any help! Wil
You could try with numerical_integral. You didn't provide definition of B(), so here is example with simpler function:
BTW: I'd like to know how to do the above without 'lambda'.
BTW2: Are you sure your integral converges at d=0?
