folderName — Folder name
string scalar | character vector
Folder name, specified as a string scalar or a character vector containing the folder name.
In most cases,
tempnamegenerates a universally unique identifier (UUID). However, if you run MATLAB® without JVM™ software, then
tempnamegenerates a random character vector using the CPU counter and time, which is not guaranteed to be unique. For more information about the MATLAB startup option that does not load JVM software, see Commonly Used Startup Options.
