[Octave-bug-tracker] [bug #63965] perms.m doesn't do "unique" for cell inputs

[Arun Giridhar]

Follow-up Comment #3, bug #63965 (project octave):


octave:1> perms ({"foo", "b", "b"}, "unique")
warning: unique: "rows" is ignored for cell arrays
warning: called from
    unique at line 135 column 7
    perms at line 114 column 9

ans =
{
  [1,1] = b
  [2,1] = foo
}



octave:2> unique (perms ({"foo", "b", "b"}), "rows")
warning: unique: "rows" is ignored for cell arrays
warning: called from
    unique at line 135 column 7

ans =
{
  [1,1] = b
  [2,1] = foo
}


The patch attached in comment #1 works for small inputs by exhaustive checks
but a better solution is needed, one that can accommodate large inputs as
well.
