How to cut duplicate rows from a matrix

I have a matrix that has 60,000+ rows and there are duplicate of rows in this matrix example: [1 2 3; 1 2 3; 2 3 3; 2 3 3] How can I get a matrix that just has [1 2 3; 2 3 3]?

 A_uniqueRows = unique( A, 'rows' ) ;

or

 A_uniqueRows = unique( A, 'rows', 'stable' ) ;

if you don't want the output to be sorted.
