help with vectors MatLab?

Hello!

I have a vector

 H  =

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

I want it to be like

          H= 0 1 0 1 0 1 0 1 0 1 0 1......

I tried with H(:) but it wont work, there is 17 zeros and 16 ones is that maybe a problem? Hope someone can help me . Kind regards

H2 = H;
H2([1:2:end,2:2:end])=H;

this is the solution !

Your question is a bit unclear. If you want to create a vector H containing alternating 0's and 1's, starting and ending with 0 with the mentioned length you can do it like this:

 H = [repmat([0 1],1,16) 0]

If you just want to transpose H to a row vector, which will give you H = [0 0 0 ... 1 1 1...] you can do it like this:

 H = H'

As far as I know there is no build in function which will give H = [0 1 0 1 ...], for this you need some more code.

 H1 = H(1:ceil(length(H)/2)); % first half of H
 H2 = [H(ceil(length(H)/2)+1:end); 1]; % second half of H, add a 1 at the end to get equal lengths

 H=[H1 H2];

 H = H(1:end-1)' % Do not include the final 1

Yes, I would like to alternate 0's ant 1's. What if I do not know length of my vector but I know that 0's are coming first and then after them 1's.
