You didn't test the code before uploading!
I modified the input lines
z = 1; % input('Enter zeta, z = ');
w = 1; % input('Enter omega, w = ');
dt = 0.1; % input('Enter delta_t,dt = ');
Tmax = 10; % input('Enter T_max, Tmax = ');
Added
t_i = t;
before the while-loop. And commented out
% Excit;
since it only contained comments. And modified the last statement in the while-loop
t_i = t_i+dt;
Now it runs in no time
>> tic, main, toc
Elapsed time is 0.005256 seconds.

As part of the assignemtns we have to add the values for w,z, and dt in the command line since it will change in the future. This is the first time I did the coding so I am pretty new to this game.

"w,z, and dt in the command line" I guess that means you should convert the script to a function, see Scripts vs. Functions.
