查找excel中多列中出现的值

Question

我有一组基因探针，当置于不同的化学应激下时会被上调。每列包含所有上调的基因探针。我有12列，如何获得所有12列中出现的基因探针列表？

我已经能够使用公式

找到两列之间的相似性

 =IF(ISERROR(MATCH(A2,$C$2:$C$21473,0)),"",A2)

但无法解决如何使其适应12列

G.Ac  G.As  G.At  G.Ac.At  G.As.Ac  G.As.At G.Cd  G.Cu  G.Ni    
G.Cd.Cu  G.Cd.Ni  G.Ni.Cu

这是12列中的前8行。总共有21473行。

由于

Answer 1

您可以使用这样的数组公式来计算特定基因探针在

中出现的列数

=SUM(--(MMULT(TRANSPOSE(ROW(A$2:L$10000)^0),N(A$2:L$10000=A2))>0))

这是获取2D数组的列总数的标准方法 - 在这种情况下，对应于数组元素的实例等于/不等于A2的真/假值数组。

这是一种蛮力方法 - 每行需要〜120K乘法。如果将公式复制为~10K行，则计算机上的延迟时间约为100秒，而Excel会计算出结果。

必须使用 Ctrl Shift 输入

作为数组公式输入

在这个虚拟数据中，C是所有12列中唯一出现的值。
