How can Matlab convert an array into a string?

In MATLAB, the num2str function can be used to convert an array into a string. For example, if there is an array A, you can use the following code to convert it into a string containing all elements.

A = [1, 2, 3, 4, 5];
str = num2str(A);
disp(str);

In this example, str will contain the string “1 2 3 4 5”, with elements separated by spaces. You can also use the sprintf function to convert arrays into strings with custom formats. For example, to convert an array into a string with comma separators, you can use the following code:

A = [1, 2, 3, 4, 5];
str = sprintf('%d, ', A);
str = str(1:end-2); % 去除末尾的逗号和空格
disp(str);

In this example, str will contain the strings 1, 2, 3, 4, 5.
