Hello,
say, A==[0,0,1,2,3,3,6,6; 8,4,5,6,7,7,8,2; 9,9,10,10,11,12,22,45; 0,1,0,2,7,8,16,17; 0 0 0 0 0 0 1 1];
I need to delete the entire rows if any one of them happens:
a) column 1= column2
b) column3 =column4
c)column5 = column6
d)column7 = column8
e) column 5=column8
so finally, i''ll get,
A= [0,1,0,2,7,8,16,17]
Could you please help me knowing this how to do?

out = A(all(A(:,1:2:end) ~= A(:,2:2:end),2),:)
