Hi everyone,
Thanks for looking into my problem. I am resending the code so that the problem
becomes clear. I hope it is a bug that can be fixed soon so I can start
plotting correctly again. I also have problems with mesh as I said before.
N = 10; l = 0.6; niter = 10; deltaT = 0.0017778;
t= (niter)*deltaT;
x =linspace(0,l,N);
y= linspace(0,t,niter);
vvvv =
