How to truncate this matrix

I have a sorted 15*3 matrix as follows:

a=[  4     3     2;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   3     3     3;
   2     3     4;
   2     3     4;
   2     3     4;
   2     3     4]

how can I transform this matrix to a new matrix where the vectors with more than 1 duplication will be omitted so as in the final matrix only exclusive vectors with no repetition is generated. for instance instead of 10 repetition of vector 3 3 3 only one vector is generated in the new matrix. In other words, how the above matrix can be transferred to [4 3 2; 3 3 3; 2 3 4] ?? thanks
