I am struggling with a simple recurring function
What is a recurring function? Do you mean looping?
Here is the script. T(i) are trees (as in graphs).
The program operates great, until the step where
norm_ted is calculated. Mysteriously norm_ted becomes
0, even though "mag" value is calculated correctly.
Also, strangely, sum_norm_ted also becomes zero.
What am I missing?
Do you mean for sum_norm_ted to be the sum over all i and j? If so, you
should initialize it before the start of the outer loop.
I don't know why you are getting 0 at the end of the loop. It is as if
sum_norm_ted and norm_ted are initialized but the inner loop doesn't
run. Is this the exact code that you have trouble with?

Thanks.
