Re: removing replicated rows from a (large) matrix

[Etienne Grossmann]

  Hello,

  are you sure it works? I renamed it joao_uniq, and it gives :

octave:144> x(1:15,:)' , x(joao_uniq (x(1:15,:)),:)'
ans =

  0  0  0  0  0  0  0  0  0  0  1  1  1  1  1
  1  1  1  2  3  4  5  6  9  9  0  0  4  5  5

ans =

  0  0  0  1  1
  1  1  9  0  5

  isn't there a problem?

  For the same effect, you can use uniq(), from my "misc" toolbox, after passing
the data to sortrows (Paul Kienzle's) or lexicosort() ("misc" toolbox).

  Etienne

ps : I think unique() is used as a synonym to create_set() (or almost)
