Hello,
I'm having trouble trying to get certain matrix columns. Let's say I have Matrix A:
A = [1 2 3 4 5 6 7 8 9 10 11 12; 13 14 15 16 17 18 19 20 21 22 23 24]
Let's say I'd like to get every third value starting in position 1. Then I would use this code:
A(:,1:3:end)
My issue is that I'd like to skip four positions and get the next two. This would be my output if I started from the first position:
Output = [1 2 7 8; 13 14 19 20]
I could get every column manually but since I'm working with big matrixes and different sizes it woldn't be convininient.
Can someone come around a solution for this?
Thnak you in advance,
Santos
