need help Coding this on Matlab, need to see the codes and step by step for # 1-7 please. thank you

Laplace Transform Worksheet Case 1 - Real-Valued Poles. Use partial fraction expansion to find the inverse Laplace transform of each of the following. For each case, find all finite poles and zeros and plot their location in the s-plane. Use Matlab to plot the time functions. Qualitatively, how does the zero location affect the time response? 1.
