uM = null(P,'r')
I = transpose(uM)
%sys2 = tf( sys );
t = linspace(0, 2.5, 10).';
x_zero = transpose([0,0,0,-0.1333])
u = x_zero.*exp(-14.5*t)
x0= initial(sys,x_zero)
[y,t] = lsim(sys ,u , t)
error that I am receiving:-
Matrix dimensions must agree.
Error in antiresonance_part_two (line 36)
u = x_zero.*-exp(-14.5*t)

See my Answer to your duplicate Question how to simulate using lsim command I am receiving error because of variable 't'(time). It took a few minutes to find out what the problem was and then propose a solution.
