X=[3 5 ; 1 2 ; 5 6 ; 3 5 ] How to make like Y=[3 5; 1 2; 5 6] ie; representing [3 5] for single time rather displaying it twice

You can use unique.

See the 'rows' option.

That is why the link leads you to the 'rows' flag example:

[C,ia,ic] = unique(A(:,1:2),'rows')

In your case:

X=[3 5 ; 1 2 ; 5 6 ; 3 5 ];
Y=unique(X,'rows','stable');
