Question

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.

Answer 1

You can eliminate elements like this:

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