Tradeoffs: Code complexity vs data storage

 This video discusses a code tradeoff of increasing code complexity so that less data needed to be stored. This video discusses how for small cases, code complexity often rules over other considerations. However, in this case, the memory requirements grow a the cube of the size of a matrix, so quickly the code complexity must be sacrificed.

    If i have a data set of 5000 rows and 14 columns, what command(s) should I use if I want to find the average of all five thousands rows across columns 7-10.

    Thank you,
    Toon

    mat = rand(5000,14);
subMatrix = mat(:,7:10);
avg = mean(subMatrix(:));

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).
