_ArrayUnique

[BrewManNH]

It states in the help file that _ArrayUnique "Returns the Unique Elements of a 1-dimensional array.", fundamentally this is incorrect. What _ArrayUnique does is it returns a 1-dimensional array, while the incoming array can be multi-dimensioned. If you use the $iDimension parameter you can tell it to only return the unique items on whichever column you'd like.

See the example below, it will return the unique items from the 3rd column (first column is 1 when using _ArrayUnique)

#include <Array.au3>
Local $Array[4][6] = [["FirstName", "LastName", "IDNumber", "Location", "Grade", "Action"],["john", "smith", "111222", "Denver", "2", "enroll"],["jack", "jones", "333444", "denver", "4", "withdraw"],["jack", "jones", "333444", "lasvegas", "4", "enroll"]]
_ArrayDisplay($Array)
$Array = _ArrayUnique($Array, 3)
_ArrayDisplay($Array)

It would be nice if the documentation could be changed to reflect the true usage of the function.

"Returns the Unique Elements of a 1-dimensional array."

Not to mention the fact that is not returning "the Unique elements", but returning a version of the input with the duplicates removed. ("make elements unique" versus "give unique elements from set")

$aArray = [1,2,3,4,5,1,2,3,4,5]  [Array|10]
$aNewArray = [5,"1","2","3","4","5"]  [Array|6]

_hehe

Oh yea, real reason.

$iDimension [[optional] The Dimension of the Array to use

1 - double "[" character typo.
2 - dimension?, Field/Column (or Row?, I'm never sure about those.) sound more appropriate.
