Thanks for the clarification! I'll try to do this :)

comment Solving recursions
Works, but calculating 16 points took ages (for u3). I got to 11 points. Is there a way to optimize the code? Make it run in steps. Like first solve the initial one, assign it to u3[1], then use this in another loop and so on? Because I feel like currently it's doing all things at once, and that makes it stall. And this is for 16 points (very crude scale). I'd like to have finer division (nicer plot).

Ok, this seems to fix the issue, I'll try to run it, and see what I get.

I'm still not quit there yet, but if I find the complete solution I'll be sure to post it :)

comment Method of characteristics, recursion formulas
I think I solved the recursion problem. I just changed the lists to a parameters that I can extract from the lists, e.g. AR[n] and \delta t[n], then I can get the table of all the values, and solve each in order.

comment Method of characteristics, recursion formulas
I've tried to include all the necessary info, the thing that bothers me is that the A_R is a list, and when I try to evaluate my recursion formula, this list is making a problem. I'll look into Nest and Fold and see how I can use them.

comment FeynArts not working properly
Yeah, I cannot log in there. I also tried resetting my pass, but for some reason I don't get anything in my mailbox (I checked all mails just to be sure) :\

Yup that works, just like Peltio suggested :)
