Write new file in different directory

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

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
