MATLAB 在字符串元胞数组的每个字符串末尾添加一个字母

Question

假设我有一个字符串元胞数组：

A = {'hello','world','how','are','you'};

我想在每个字符串的末尾添加字母z，以获得：

Az = {'helloz','worldz','howz','arez','youz'};

我正在使用 for 循环来完成此任务，但我想尽可能地改进它。

这是我目前使用的代码：

Az = cell(size(A)); % Preload
for i = 1:size(A,2)
    Az{i} = [A{i},'z'];
end

有什么建议吗？

Answer 1

strcat 就是这样做的：

Az = strcat(A, 'z');

来自documentation,

s = strcat(s1,...,sN) horizontally concatenates strings s1,...,sN. Each input argument can be a single string, a collection of strings in a cell array, or a collection of strings in a character array.

If any input argument is a cell array, the result is a cell array of strings. Otherwise, the result is a character array.

For character array inputs, strcat removes trailing ASCII white-space characters: space, tab, vertical tab, newline, carriage return, and form feed. For cell array inputs, strcat does not remove trailing white space.
