Get unique values in matrix with Matlab

Question

I'm looking for fastest way to get unique values in matrix with Matlab! I have a matrix like this:

1       2
1       2
1       3
1       5
1       23
2       1
3       1
3       2
3       2
3       2
4       17
4       3
4       17

and need to get something like this:

1       2
1       3
1       5
1       23
2       1
3       1
3       2
4       3
4       17

Actually I need unique values by combination of columns in each row.

Answer 1

Have a look at matlabs unique() function with the argument 'rows'.

C = unique(A,'rows')
