Basics: Making a vector the MATLAB way

 I recently received an email asking me a question about how to create an array that is composed of different outputs from functions. The user was new to MATLAB, but had a background in programming other languages. This was evident in his code, which used the scalar approach required of languages like C. In this video, I show how we can use vector indexing in MATLAB to express his code in a much more natural way.

Doug first used MATLAB in 1994, could not figure it out until he got some help in 1995. He is now dedicated to making sure that no one else wastes a year of their life not knowing MATLAB like he did.

    How about just doing this…

    vec=[1 2 sin(3:6) cos(7:10)];

    John,

    That works well also.

    As you can guess, this was an extreme simplification of a much larger problem that someone had asked me. If the problem were really this simple, I would do just as you say. I was hoping to show the general concept in a simple manner that would scale well for the original problem.

    Thanks,
    Doug

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).
