MATLAB: How to check if each two successive rows are identical

identicalunique

Hello,
Suppose that we have the matrix A(300*100) where each two "successive" rows should be identical, So I want to get another matrix B(150*1) where the first element is one if row 1 and row 2 are identical. And in the second element is zero if row 3 and row 4 are not identical. Can anybody help me in that?
regards,

Just use basic indexing and logical operations:
>> A = [1,2,3;1,2,3;4,5,6;4,5,7]
A =
   1   2   3
   1   2   3
   4   5   6
   4   5   7
>> all(A(1:2:end,:)==A(2:2:end,:),2)
ans =
   1
   0
