function tempDir2 = tempdir2%TEMPDIR2  Return temporary directory.%		DIR = TEMPDIR2 returns as a temporary directory the directory%		<TEMPDIR>/<USERNAME>@<HOSTNAME>/MATLAB. This directory is user- and%		host-specific and thus better suited in networks/clusters than the%		temporary directory returned by Matlab function TEMPDIR.%%		Markus Buehren%		Last modified 20.04.2008 %%		See also TEMPDIR, GETUSERNAME, GETHOSTNAME.persistent tempDir2Persistentif isempty(tempDir2Persistent)		% build directory string	tempDir2 = tempdir;	tempDir2 = fullfile(tempDir2, [getusername '@' gethostname], 'MATLAB');		% if directory is not existing, try to create it	if ~exist(tempDir2, 'dir')		try		mkdir(tempDir2);		catch			error('Unable to create directory %s.', tempDir2);		end	end	% save string for next function call	tempDir2Persistent = tempDir2;else	% return string computed before	tempDir2 = tempDir2Persistent;end
