Please write a script file for Matlab. Thank you!!!

e An under-damped harmonic oscillator is given by the equation x(t)= e al cos(10t), where eat is the envelope function that limits the amplitude of oscillation. For a = 0.01, 0.5 and 2.5, generate 3 by 1 subplots of x(t) as a function of time for t between 0 and 10. Using dashed lines, overlay on the same plot the two envelops (one above and one below the x = 0 line)
