Hello to everyone, i have got this vector and i want to split it in blocks 0f 3 elements:


noise = 1 1 1 1 0 0 0 1 1 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 1 1 1 1


round(length(noise)/3)=9


x=reshape(noise(1:27),9,[])

x =

1 1 0
1 1 0
1 1 0
1 0 1
0 0 1
0 0 1
0 1 1
1 1 1
1 1 1

But the problem is that i am interested in this vector:

x' =111
100
011
111
000
111
000
111
111

How can transform x in x'?

Thanks in advance.

This seems to do it:

reshape(noise(1:27), 3, [])'
