How to create a char array in Matlab?

In MATLAB, you can use the following syntax to create a char array:

% 创建一个空的char数组
charArray = char([]);

% 创建一个包含指定字符的char数组
charArray = 'hello world';

% 创建一个包含指定字符串的char数组
charArray = char('hello', 'world');

You can also convert a string to a char array using the str2char function.

str = 'hello world';
charArray = str2char(str);

Please note that a char array is a two-dimensional array where each element is a character. You can use the disp function to display the contents of a char array.
