Hi,
I don't know the code to put in the EDITOR to find the maximum value of a function.
My EDITOR:
%Function i=@(t,y) [y(3); y(4); (-xg0*w0^2*sin(wf*t)*M-w0^2*y(1)*M-2*w0*beta*y(3)*M)/M; 0]; [Ti,Yi]= ode45(i,[0 50],[0 0 0 0]);
%Plot function plot(Ti,Yi(:,1));
%Find max value of the function ?

Why not use max, e.g.,
max(Yi(:,1))
For details, see the documentation
doc max
