MATLAB: Question regarding ‘copyfile’ function from folder to folder

This is exactly, what you find in the documentation. Please read:

help copyfile
doc copyfile
[SUCCESS,MESSAGE,MESSAGEID] = copyfile(SOURCE, DESTINATION) attempts to
    copy SOURCE to DESTINATION. If SOURCE constitutes a directory or
    multiple files and DESTINATION does not exist, copyfile attempts to
    create DESTINATION as a directory and copy SOURCE to DESTINATION. If
    SOURCE constitutes a directory or multiple files and DESTINATION exists
    as a directory, copyfile attempts to copy SOURCE to DESTINATION.

This means, that copyfile copies the files from the source directory to the destination directory. This sounds intuitive for a function, which is called "copy file".
