Hello,
I wonder if it is possible to disable the sort-function of the Union command?
If not, can someone give me a short and nice procedure f, that can get the
union of a list with the original order preserved (the first apperance
should be left in the list). I'm not interrested in Do-loops solutions and
and similar procedures (I can do that myself)
example
in:
f[{5,4,3,4,1,6}]
out:
{5,4,3,1,6}
Thanks in advance
