I really do not understand what this question says to me. In those quarantina days, I am trying to learn matlab by myself by using Tobin's book. thus, I have no body to ask directly this question. Therefore, I posted this question without any my solution trial. sorry for that. any help, any suggestion any hint to give a way to solve this question will become very useful for me. Many thanks.
