The closed-loop transfer function of a sampled data system is given by

(a) Compute the unit step response of the system using the step function,
(b) Determine the continuous- time transfer function equivalent of T(z) using the d2c function and assume a sampling period of T = 0.1 s.
(c) Compute the unit step response of the continuous (non sampled) system using the step function, and compare the plot with part (a).
