What's wrong with this MATLAB code for Rutherford scattering, it won't run for me! :( Hi, I can't do matlab...and have to plot the trajectory of alpha particles in rutherford scattering. I've made an attempt, but i know i've gone wrong somewhere. Could someone tell me how to fix it? I'd be SOOOO thankful...you've no idea!! This is what i have so far, i've added it as an attachment as an m file. I want it to look something like this: http://www.kutl.kyushu-u.ac.jp/seminar/MicroWorld1_E/Part2_E/P25_E/Rutherford_S_E.jpg [Broken] (and know the way i have it, there should only be one trajectory...i just want it to run! then i'll do it for other impact parameters too. Thank you so much in advance!
