to combine different vectors with the same element

In matlab, which command can combine different vectors, and form a new vector like a boolean merge,for example, I have three vectors,[1 2 3 4], [2 4 5],[ 1 5 6],by using this command, a new vector [1 2 3 4 5 6]is formed, where only one of the same elements is left and these element are in series from small to large

out=union([1 2 3 4], union([2 4 5],[ 1 5 6]))

%or

out=union([],cat(2,[1 2 3 4], [2 4 5],[ 1 5 6]))'

Thanks very much! It is very helpful

Answer 2

A completely unique experience:

three_vectors = [[1 2 3 4], [2 4 5],[ 1 5 6]];
new_vector = unique(three_vectors)

new_vector =
     1     2     3     4     5     6
