Also Implement this in Matlab Example 3.4 which i am gonna attach down here. I need matlab code with short summary of its solution. I have attached example on which we have to implemet our question.

Example 3.4 Use MATLAB symbolic computation to find the Laplace transform of a real exponential, x(t)=e-a(t), and of x(t) modulated by a cosine or y(t) = e-cos(10t)u(t). Plot the signals and the poles and zeros of their Laplace transforms Example 3.4 Use MATLAB symbolic computation to find the Laplace transform of a real exponential, x(t)=e-a(t), and of x(t) modulated by a cosine or y(t) = e-cos(10t)u(t).
