How do you save a new audio file from a sound on matlab?

Hi, I'm trying to write use matlab to take some sound files, trim them to the same size, and save them into a completely new folder with new names without overwriting the original. I've been trying to use audiowrite, but it gives me an error:

Error using audiowrite
The value of 'filename' is invalid. Expected input to be one of these types:
char
Instead its type was double.
Error in audiowrite>parseInputs (line 226)
parse(p,filename, y, Fs, pvpairs{:});
Error in audiowrite (line 103)
props = parseInputs(filename, y, Fs, varargin);

This was after using the code audiowrite(anna_ten10, trimmed_anna_ten10, 44100) where anna_ten10 was the original file that was trimmed, trimmed_anna_ten10 was the trimmed file that I would like to make into a seperate file, and 44100 was the fs. I'm not sure what to put in place of anna_ten10, since I don't want that file to be overwritten, but I've tried putting the new folder directory there and it isn't saving. What should I do?
