is a suitable destination for temporary data. For example, if you
need to store some data in a temporary file, then you might issue

fileID = fopen(tempname,'w');
In most cases,
tempname generates a universally
unique identifier (UUID). However, if you run MATLAB® without JVM™,
tempname generates a random name using the
CPU counter and time, and this name is not guaranteed to be unique.
Some systems delete temporary files every time you reboot the system. On other systems, designating a file as temporary means only that the file is not backed up.
