Scilab Prog: To plot time response of a system with impulse input

Answer to query raised by a student from already given practical list  in the class  ( JAN  2020)

Plot the same for the following  TFs

1. C(s)/R(s) =   (s+1)/[s(s^2+2s+5)]
2. C(s)/R(s) =   (s^2+1)/[s(s^3+2s^2+5s+1)]

   Note: From these plots also explain either the system is stable  or not
