Linearly Spaced Vectors

(Originally posted on Doug's MATLAB Video Tutorials blog.)

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]
