removeDuplicates doesn't seem to work

[Alexis BRENON]

removeDuplicates doesn't seem to remove anything...

Example:

th> x = torch.rand(1,5)
                                                                      [0.0000s]	
th> y = x:repeatTensor(5,1)
                                                                      [0.0005s]	
th> print(y)
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
[torch.DoubleTensor of size 5x5]

                                                                      [0.0005s]	
th> manifold.removeDuplicates(y)
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
 0.0463  0.4599  0.1440  0.2752  0.2289
[torch.DoubleTensor of size 5x5]

{
  1 : 1
  2 : 2
  3 : 3
  4 : 4
  5 : 5
}
                                                                      [0.0012s]	
th> 

As you can see, all samples of y are returned while I expect to get only one (as they are all the same).
Do I misunderstand the use of this function ?

Kind regards,
Alexis.
