How to check if each two successive rows are identical?

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,

Sppose that:

A=[ 1 2 3 ; 1 2 3 ; 4 5 6; 4 5 7]

The matrix B(2*1) should put "1" in the first element because row1 and row2 in A are identical. Also it should put "0" in the second element because row3 and row4 in A are bot identical.

So B:

B=[1;0]

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
