help in 1 & 2 please !

I need a matlab conding for this questuion to determine the min and max of the function

- Objective Function Ctotal=Cm(24(Dtank)2t+[4(Dtank)24(Dtank2t)2](Ltank2t))+Cw(2Dtank+2[Dtank2t]) - Variables - Dtank - Ltank - Constraints - Ltank2m - Dtank1m - 4(Dtank2t)2(Ltank2t)=0.8m3 Figure 1. Slide 22 from "Lesson 04 - Optimization" slide deck. Your goal is to do two things with your MATLAB File(s) 1. Solve the optimization problem (minimize cost) using thle fmincon algorithm in MATLAB. 2. Conduct sensitivity analyses on the length and diameter values that minimize the cost, to show the effect of the independent variables on the objective function. Your sensitivity analyses are best illustrated using a plot. Note that you must still satisfy all the constraints in this sensitivity analyses. Clues are available in the attached spreadsheet
