Using a For Loop to Access Array Values
 
09:32
You can use for loops in MATLAB to access certain elements of an array. In a lot of cases, MATLAB does this kind of thing on its own, but occasionally there are things you can't do with built-in functions.

MATLAB - Episode 4 - Indexing
 
05:11
Hello, and welcome to another episode of the Software Carpentry lecture on MATLAB. In this episode, we'll have a look at some of the ways you can index arrays. As we'll see, clever indexing allows you to avoid writing loops, which both reduces the size of your code, and makes your code more efficient. Visit the Software Carpentry page for this episode at: http://software-carpentry.org/4_0/matlab/indexing

Learn how to remove an element from a vector in Matlab by referencing the position of the element and changing the value. To remove the second element in vector a = [3,4,5,7,9] a(2) = [] This will make the new vector a = [3,5,7,9] Note that the length of the vector has also changed to be of dimensional length four.
