A function that inserts an element into an array

So I am doing my homework on MatLab and I am baffled by this question given. It is to write a script that enters an element into an array at an index.

The array(A)'s size is 1 by N. The element(e) is the value that is entered. index(i) is the ith position of the array.

No specific array is provided.

All I know is that after the element has bee added the size of the array is now 1 by (N+1)

But beyond this, I don't even know where to start.

Please help! (explanation would be appreciated too!)

Most likely you will need to use indexing. Show us what you have tried so far.

This is what I have so far. I have no idea how to start the script and I have no idea how to index

Hints:

1. To get length of an array use length.
2. To get dimensions use size.
3. If you have an array a, to access ith element: a(i)
4. I can join two rwo arrays using [a b]
5. I can join selected elements of a using [a(1:3) a(4) a(5:end)]

Try all the above steps in command window, you will get an idea how to complete your Home Work. Concentrate on the 5th point.
