Here is my question please take your time

Please Write your code in Matlab to evaluate the output of the unknown system from Semmlow Ex 5.1 (unknown_sys5_1.mat code in appendix) according to 1) an impulse, 2) a unit step input, and 3) a ramp input with a slope 1. The code should be able produce a single figure with two horizontal subfigs, one for input functions, and one for output waveforms. Both should have labeled x and y axes, titles, and is able to demonstrate three normalized functions/waveforms in time. Please start with the code in the images below also please write the code in plain text much appreciated

here are the images below take your time
