MKDIR Make Directory

Section: Operating System Functions

Usage

Creates a directory. The general syntax for its use is
  mkdir('dirname')

which creates the directory dirname if it does not exist. The argument dirname can be either a relative path or an absolute path. For compatibility with MATLAB, the following syntax is also allowed

  mkdir('parentdir','dirname')

which attempts to create a directory dirname in the directory given by parentdir. However, this simply calls mkdir([parentdir dirsep dirname]), and if this is not the required behavior, please file an enhancement request to have it changed. Note that mkdir returns a logical 1 if the call succeeded, and a logical 0 if not.
