查找哪个字母出现次数最多 [英] Finding which letter has maximal occurence

问题描述

我尝试了Matlab和网络来寻找答案，但徒劳无功，所以我需要您的帮助 我使用下面的代码来查找数组中字母的出现次数；

I tried Matlab and the net to find an answer but in vain so I need your help I have used the code below to find number of occurrences of the letters in an array;

characterCell = {'a' 'b' 'b' 'a' 'b' 'd' 'c' 'c'};  %# Sample cell array 
matchCell = {'a' 'b' 'c' 'd' 'e'};                  %# Letters to count      
[~,index] = ismember(characterCell,matchCell);  %# Find indices in matchCell 
counts = accumarray(index(:),1,[numel(matchCell) 1]);  %# Accumulate indices 
results = [matchCell(:) num2cell(counts)] `

结果=

'a'    [2] 
'b'    [3] 
'c'    [2] 
'd'    [1] 
'e'    [0] 

现在我需要知道哪个字母出现次数最多 如何知道索引?

Now I need to get which letter has the highest occurrence How to know the index?

推荐答案

索引是函数max的第二个输出.

The index is the second output of the function max.

所以您应该这样做:

[~,index]=max(counts)
mostCommonLetter=matchCell{index};
