I understand the point of asking a question is to not automatically be given the answer. However I have no clue how to even approach the given questions that are mentioned below. I looked up a way to do it on the Matlab website already but am lost.

1.) Create a program to determine test grades based on the score and assuming a single input. The grades should be based on the following criteria -

--- Grade--------- Score--------

-------A-------------90 to 100-----

-------B-------------80 to 89------

-------C-------------70 to 79------

-------D-------------60 to 69------

-------E---------------<60----------

2.) Create a program that prompts the user to enter his or her year in school – freshman, sophomore, junior or senior. The input will be a string. Use the switch/case structure to determine which day finals would be given for each group – Monday for freshmen, Tuesday for sophomores, Wednesday for juniors and Thursday for seniors.

3.) Create a program using for loop to calculate the factorial of an inputted number.

4.) Repeat the above problem using while loop.

Answer 1

[Ahmet Cecen]

Create the functions first:

function letter = grade(points)

   if this

      letter = that

   else if this

      letter = that

so on.

Same with case structure for 2, for loop for 3, while loop for 4.

Answer 2

[Thorsten]

function g = grade(num)

if num < 60
  g = 'E'
elseif num < 70
  g = 'D'

and so on.

Another helpful snippet you can adapt:

buttonNumber = menu('Enter your class', 'Freshman', 'Sophomore', 'Junior', 'Senior')
switch buttonNumber
  case 1
