MATLAB: Get row no where comparison gives 1

cell arrays

Hey i have a cell array:
     A={[4x9 cell],[3x9 cell],[2x9 cell]}
   A{1,1}= [1,-0.03,0.1,1.3,0,0.23,1,0,0.2; 1,0.6,0.14,2,0,0.6,0.6,0,0.6; 1,-0.15,0,1.4,0,0.35,1,0,0.38; 2,-0.2,0.18,3,0,0.4,0,0,0.4];  similarly values for A{1,2} and A{1,3}
I have compared each row of A{1,1} with every other row in A{1,1} using
   A(1:end-1,:)<A(2:end,:)
Now what I want to find is that how can I get the row no's which are being compared at a particular time. For example if row 1 and row 2 are being compared how can I get 1 and 2 in result.
I want to store all elements where result of comparison is 1. for example if row 1 and row 4 gives 1 in result then I want to store the row no where the result is 1 ( like 1 and 4 in this example).
please help.

Best Answer

repmat((1:size(A,1)-1).', 1, size(A,2)) .* (A(1:end-1,:)<A(2:end,:))
which would give you
     0     1     1     1     0     1     0     0     1
     0     0     0     0     0     0     2     0     0
     3     0     3     3     0     3     0     0     3
for whatever good that would do you.
