I have zero coding experience. What exactly is a character array, and how does it differ from a number array? I know in some code like the 'disp' function you use num2str[x] to convert a number array to a character array. What exactly is that doing? The entire concept confuses me.

Whoever told you that you need to use num2str in order to display a numeric with disp is wrong:
>> disp([1,2,3])
1 2 3

These links might be helpful for understanding data types in MATLAB, as well as classes in general:
The data type of a variable impacts its size, precision, possible values, and the operations that can be performed on it. Certain functions can only be performed on certain data types.
