I want to create a new file in a directory other than the current opened directory.
My code:
f='somefilename'
fid = fopen(f,datadirectory,'w');
where datadirectory is the directory where I want to write my file. But it throws an error.
Can somebody please help? Thank you.

filename = fullfile(datadirectory, f);
fid = fopen(filename, 'w');
Note: you mention "text file" in the tags. If you are using MS Windows then it would be common to use 'wt' instead of 'w' when created text files. Using 'wt' tells it to use Carriage Return / Linefeed pairs for the line, which is needed if you want compatibility with older programs such as Notepad

Hi. Thanks for the answer but it still shows the same error. I want to save the file in the different directory. What I am guessing is matlab gives an error because it can't read the file in the working directory. Error: Invalid file identifier. Use fopen to generate a valid file identifier.

You should use
filename = fullfile(datadirectory, f);
[fid, msg] = fopen(filename, 'w');
if fid < 0
error('Failed to open file "%s" because: "%s"', filename, msg);
end
