MATLAB Basics: Linearly spaced vectors

When I look at code written by new users, sometimes, I will see code like this:

a = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15];

There is an easier way:

a = 1:13;

This three minute video shows how to use commands like linspace and the colon operator to make vectors like:
[1 2 3 4 5] or [-1 -0.5 0 0.5 1].

    Excellent, thanks a lot!

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
