How to run function between each row

Hi all. I have a matrix 7-by-256 and I need to run my funtion between each row like this: row1 row2; row1 row3; row 1 row4; etc... And save the results.

How do I specified that in for loop?

pairs=nchoosek(1:size(data,1),2);
for n=1:size(pairs,1)
    row_a=data(pairs(n,1),:);
    row_b=data(pairs(n,2),:);
    %calculate results here
end

I'm completely new with matlab, so maybe you can walkthrough a bit. I don't understand what are and what happens in row_a and row_b

On those lines I index the 7x256 array so you have two variables, each containg 256 values. That way you can do the calculations you need. In the first iteration row_a will contain the first row and row_b will contain the second row. The next iteration row_b will contain the third row, etc.

If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks).
