% MKDIR MKDIR Make Directory
% 
% 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.
function status = mkdir(parentdir,dirname)
  if (~exist('dirname'))
    status = mkdir_core(parentdir);
  else
    status = mkdir_core([parentdir dirsep dirname]);
  end
