1- Create a new script that is called HW10a.m and save it. The script will do the following: Assign x to the input statement that states the following: 'Enter the value of the diameter:' Declare a sequenced vector t that starts from 0 to 2 with step size of 0.001. Using if-elseif-else statement that would do the following: a. b. c. If 0 20 then plot f(t) = 5cos(10t)*exp(-2t) and show the grid. Hint: use index multiplication for f(t) 10 then plot f(t) = 5exp(2t) and show the grid. i. ii. iii. iv. Else display a message 'Error. The diameter must be a positive value d. Test your code for each of the cases and upload your script as a.m file. 2- Create a new script that is called HW10b.m and save it. The script will do the following: a. Create a random number that goes from O to 5 and assign it to a variable y using the following command y round(rand(1,1)*5); b. Use a switch-case statement that would switch on y such that it will evaluate the following cases: Case 0 display The random number is 0, Case 2 display The random number is 2, i. ii, iv. Otherwise display The random number is odd, c. Test your code for each of the cases and upload your script as a .m file
