A=[1 2 3 4 5;
1 2 3 4 6
1 3 4 5 8];
i want a output like X=[1 2 3 4 0]

X = zeros(1, size(A,2));
mask = A(1,:) == A(2,:) | A(1,:) == A(3,:);
X(mask) = A(1,mask);
mask = A(2,:) == A(3,:);
X(mask) = A(2,mask);

I suspect this is a homework assignment so I'm only going to give a hint. You want the most common element as long as it appears multiple times? The mode function may be of use to you.
