Extract every element except every n-th element of vector

indexing, matlab

Solution

You can eliminate elements like this:

A = 1:100;
removalList = 1:5:100;
A(removalList) = [];

Problem

Given a vector ``` A = [1,2,3,...,100] ``` I want to extract all elements, except every n-th. So, for n=5, my output should be ``` B = [1,2,3,4,6,7,8,9,11,...] ``` I know that you can access every n-th element by ``` A(5:5:end) ``` but I need something like the inverse command. If this doesn't exist I would iterate over the elements and skip every n-th entry, but that would be the dirty way.
