I strongly suggest you to read the documentation properly before using any function.

if you are trying to use fopen() to write a file and you did not specify the path to the file, then you are probably not in a directory that you have permission to write in. The default directory when you start up MATLAB can end up being the one that MATLAB is installed in.

Do you have the fopen function shadowed by another function or variable? What does this show:
which -all fopen

Ran in:
@Alexander
That means you wrote some function named fopen. Find the function you wrote using this command:
which fopen -all
built-in (/MATLAB/toolbox/matlab/iofun/fopen) /MATLAB/toolbox/matlab/serial/@serial/fopen.m % serial method /MATLAB/toolbox/instrument/instrument/@i2c/fopen.m % i2c method /MATLAB/toolbox/shared/instrument/@icinterface/fopen.m % icinterface method
and rename the function you wrote to something else.
