Section 7.3 The `if-end` command

We’ll now get into various ways to branch your code.

The if-end command syntax in its most straight-forward form is here:

if condition
    command
    command
    ...
end

Here are some example conditions:

if (a < b)
if (c >= 5)
if (a == b)
if (0 ~= debug)
if (a ~= 0)
if ((d < h) && (x > 7))
if ((age <= 21) || (IQ> 200))

Let’s take a look at an example. Suppose you have created the following MATLAB script:

answer = input('How much chocolate have you had today (1-10)? ');
if answer<5
   disp('Oh no! Be sure to eat more chocolate!');
end

Here is what happens when you run this script:

How much chocolate have you had today (1-10)? 4
Oh no! Be sure to eat more chocolate!

Of course we might also wish for an else case and this is what the next section is about.
