The code below shows a test case. The first call sets up the three stack functions so that
they can be called. The variable stack is an array variable that holds the data. It is passed
into functions, and also its modified value returned (from two of the functions).
Implement a script that contains the following test code.
[push, pop, peek] = mystack();
stack = [ ]
stack = push(stack, 100)
>> stack = 100
stack = push(stack, 200)
>> stack = 200
100
peek (stack)
>> ans = 200
stack = pop(stack)
>> stack = 100
peek (stack)
>> ans = 100

Assignment 2: Sub-functions and Function Handles
The aim of this assignment is explore how sub-functions can be made available from a
function file, via functional handles. The aim is to implement a simple stack in a file
(mystack.m), where the main function passes back the three stack manipulation
functions. A stack is a "last in first out" queue. The function file does not maintain any
stack state, therefore the stack itself is passed in to functions, and then, when it's modified,
the stack is returned.
The file mystack.m contains the following functions:
