Can anyone help me generate code to produce this waveform graph? This is wave equation that using finite difference method. Thank you very much for helping..

Here is a simple script that will plot the function sin(L*x). Perhaps you can adapt it to plot your function u(x,t):
L = 0.5;
x = 0 : 0.1 : 60;
u = sin(L*x);
figure
plot(x,u)
