Please help me for this numerical computation question, use matlab to solve it and post the code below. The two functions that i provide here are gonna help for the question. and use it.

estimate pru s result by Kermack and McKendrick in 19 3. A famous s that kill only a small fraction of a susceptibl 7.3. e population the death rate as a function of time is well modeled by o(t) = A sech2 [B (t-C), for constant values of the parameters A, B C. Since the ch(0-1, A is the maximum death rate and C is the time of is s peak deaths. You will use this model to fit the deaths per week from plague recorded in Bombay (now Mumbai) in a period during 1906: 5, 10, 17, 22, 30, 50, 51, 90, 120, 180, 292, 395, 445, 775, 780, 780, 698, 880, 925, 800, 578, 400, 350, 202, 105, 65, 55, 40, 30, 20
