Expression evaluation in MATLAB

 MATLAB is constantly evaluating expressions and expressions within expressions. A lot of MATLAB users do not think about this, or the implications. Simple examples of using a vector as the index into a for loop instead of one that is dynamically created (1:10 for example) is shown. Also, the use of a variable as an input to a function expecting a string is shown.

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.

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).
