How to create an index based on highest number in data

I have a set of data (in a 360 * 1 vector) where i need matlab to read the first 2 lines, then assign the highest number in the first two lines a 1, and the other a 0, this needs to go on for each pair along the entire set. Any one got any ideas?

If you have the Image Processing Toolbox, you can use blockproc() to process a pair of elements before jumping to the next pair down until it's gone all the way down the vector.

A = rand(360,1)    % Random data for demo 

% Define the function that we will apply to each block.
% In this demo we will take the max value in the block
% and create an equal size block where all pixels have the max value.
maxFilterFunction = @(theBlockStructure) max(theBlockStructure.data(:)) * ones(size(theBlockStructure.data), class(theBlockStructure.data));

% Block process the vector to replace every element in the 
% 2 element block by the max of the values in the block.
blockSize = [2 1];
blockVector = blockproc(A, blockSize, maxFilterFunction) % Find elements of maxima.
% Construct output matrix.
B = [A, blockVector == A]

You'll get something like this:

B =
         0.640283956310627                         0
         0.934334009701608                         1
         0.204451403319075                         0
         0.2808222992592                           1
         0.482153166343332                         0
         0.569773626383138                         1
         0.522844388080927                         1
         0.235050800044239                         0
         0.971156620920272                         1
         0.182306414206202                         0

etc.

A = rand(10,1) ;   % random data for demo 
B = reshape(A,2,[])' ;

iwant = [B(:,1)>B(:,2) B(:,1)<B(:,2)]

Hey there KSSV, thank you for your help.

That is sort of what I want, but what I need is it to create another column next to the original number where the larger in the pair is a 1, and the smaller is a 0, so I need it to be a 360*2 array where i have the original data and then its index in the second column
