A= [1,1,4,5,6;
2,7,4,5,7;
1,1,4,2,3;]
I want the matrix to remove redundant elements based on just first three columns, so my result should be
A = [1,1,4,5,6;
2,7,4,5,7]
I tried
unique(A,'rows')
But it works for all the columns. How do I proceed with it?

[~, ia] = unique(A(:,1:3), 'rows', 'stable');
B = A(ia,:);
