多次元配列から一意の値を取得

Question

誰でも私に次の問題を解決するためにVBAコードを教えてもらえますか？

私は列にいくつかの繰り返し値を持つdataと呼ばれるこの配列があります。

入力を

data()= 

    { 

     0,0,0,a,b,a,c,b,c,d,0,0 

     0,0,0,1,2,1,9,2,9,4,0,0 

     0,0,0,r,g,r,w,g,t,w,0,0 

} 

私はdataの非繰り返される値の情報を多次元arrを移入したいですアレイ。

も：ユニークを取得するためにゼロ値を考慮していないし、それは（列が等しいため）あなたが繰り返されたものの中から選択しますその値は問題ありません

出力

arr()= 
{ 

     a,b,c,d 

     1,2,9,4 

     r,g,w,w 

} 

Answer 1

一つの方法ある多次元配列から別の多次元配列へ
（2つの辞書を使用してインナーはユニークになり、外側は文字列で保持されます）
