comparing columns in matlab

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),:)

sorry, i''ll have to put one more condition that if:

column 5=column8

then i will have to delete that row also.
