| Thank you David for having solved my problem, that example was really helpful for me. Now Mathematica creates the network graph. Regards Filippo |
| Hi everybody, I'm trying to solve analytically the wave equation in 1-D,2-D,3-D(I have already a numeric solution). I tried to solve it with the separation of variables mathod, but I can't get an acceptable solution. Could you help me please? Thank... |
| Thank you S M Blinder. Ok now I can solve the equation, but when i plot the result, it is totally different from which I obtain with NDSolveValue. What do you think about? Thank you Clear["Global`*"]; ... |
| Hi Ivan, k1 and m are two numeric variables. I tried to modify my code as you suggested and now it seems to work. That example was very useful. Thank you so much. There's only an issue: why if I change s step, the result is totally different? For... |
| Thank you Paritosh and Ivan. I have expressed L through p because of H(q,p,t)=Sum[q'[t]*p[t]] -L[q,p,t] so I wanted to solve my system in x,y,z,px,py,pz. "IndexReduction" should not be used, Mathematica gave me that suggestion because my code was... |
| Hi everyone, I'm trying to find the trajectory of an electron in a graphene lattice. I've a set of three differential equations in the three directions mx''=Fx,my''=Fy,mz''=Fz and i try to solve my system whith NDSolve and to plot the result, but... |
| Hi all, my name is Filippo. I'm an italian Electronic Engineer and I'm studying for my master degree at Calabria University. I need to use Wolfram Mathematica for academic purpose. I hope to find useful advices and examples which could help me to... |
