`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Brother I guess something is missing. Below is the basic matlab code for springmass

clc
clear all
m=1;
c=1;
k=1;
tspan=[0 30];
y0=[0;0];
unforced1=@(t,y) [y(2);(901*cos(3*t)+900*exp(-t/5)*cos(3*t)-(10*y(2))-(226*y(1)))];
[t,y]=ode45(unforced1,tspan,y0);
plot(t,y(:,1));
grid on
xlabel('time')
ylabel('Displacement')
title('Displacement Vs Time')
hold on;
fprintf('The maximum amplitude is %f',max(y(:,1)))

Kindly revert for any queries

Thanks.
