Matlab CellFun在函数strfind上 [英] Matlab cellfun on function strfind

问题描述

我想在strfind函数上使用cellfun函数在另一个字符串单元格数组中查找字符串的单元格数组中每个字符串的索引，以将其从中排除.

I want to use cellfun function on strfind function to find the index of each string in a cell array of string in another cell array of strings to exclude them from it.

strings = {'aaa','bbb','ccc','ddd','eee','fff','ggg','hhh','iii','jjj'};
excludedStrings = {'b','g','h'};
idx = cellfun('strfind',strings,excludedStrings);
idx = cell2mat = idx;
idx = reshap(idx,numel(idx),1);
idx = unique(idx);
strings(cell2mat(idx)) = [];

cellfun呼叫行中有错误，我该如何解决?

There's error in the cellfun call line, how can I fix this?

推荐答案

这里很可爱:

strings = regexprep(strings, excludedStrings, '');

故障:

• 要搜索的所有单词/字符都传递给regexprep
• 此函数用空字符串('')替换上面给出的集合中每次出现的 any 单词/字符.

• All the words/characters to search for are passed on to regexprep
• This function replaces every occurrence of any word/character in the set given above, with the empty string ('').

它将自动对单元格数组string中的所有元素重复此操作.

It will automatically repeat this action on all elements in the cell-array string.

如果您还希望从单元格string中删除任何空字符串，请在上面的命令之后执行此操作:

If you also wish to remove any empty strings from the cell string, do this after the command above:

strings = strings(~cellfun('isempty', strings));
