Adapt the code from the notes for use with your complex number types. 5.Repeat 3 by evolving psi(x, 0) in time by solving equations (7), (9) and (10) in the notes using your solver from 4. above. I used t = 0.001. Note V (x) from the notes is 0 everywhere in this part but include it in you program because you need it for the next bit What I don't understand is the fifth question, what do they mean by "evolve in time"? I thought it meant to plot psi(x,t) for different values of t but how can that be possible if they have already given me that t = 0? Even if I did that i would need values of R in order to solve for the psi vector, where do I get that? Can somebody explain to me what question 5 wants me to do, I am not a Physicist so very complex explanations will probably not be understood.
