convert char array to string

between 2019b ans 2021b, function "fileparts" returned String instead of char, this caused many change in my code. iIs there away to obtain the legacy behavior in 2021b ?

The function fileparts creates output with the same data type as the input.

% String input = string output
fileS = "H:/user4/matlab/myfile.txt";
[filepath,name,ext] = fileparts(fileS)

filepath = "H:/user4/matlab"

name = "myfile"

ext = ".txt"

% Char array input = char array output
fileC = 'H:/user4/matlab/myfile.txt';
[filepath,name,ext] = fileparts(fileC)

filepath = 'H:/user4/matlab'

name = 'myfile'

ext = '.txt'

Check what you are using for input. You could use the convertStringsToChars function to convert your input to fileparts to char if necessary.

B = convertStringsToChars(A)

[filepath,name,ext] = fileparts(convertStringsToChars(fileS))

filepath = 'H:/user4/matlab'

name = 'myfile'

ext = '.txt'

Or simply char(string), as Fangjun showed

[filepath,name,ext] = fileparts(char(fileS))

filepath = 'H:/user4/matlab'

name = 'myfile'

ext = '.txt'

char(fileparts(...))?
