%This is Example Program #1
%This program displays "hello, world" to the command window and gets the
%user comfortable with commenting

%Comments are completley ignored by the program and the only benefit of
%commenting is to make your code as clear as possible to another person
%reading your code.

%---------------------------------------------------------------------------------------
disp('hello, world') %disp is a function and requires a string argument 
%(arguments is a fancy word for what you will input into a function)
%---------------------------------------------------------------------------------------
% a string is a group of characters, essentially just words.
% a function requires arguments to evaluate this is different from a
% command. A command requires no arguments ex.) clear, clc, close all
