I think I may have found a mistake in the 'PollMethod' option for Pattern Search. From the help for 'psoptimset', the possible options for the polling method are:

[ 'MADSPositiveBasisNp1' | 'MADSPositiveBasis2N' | 'GPSPositiveBasisNp1' | {'GPSPositiveBasis2N'} ]


However, when trying to set the option as 'GPSPositiveBasis2N' which is apparently the default anyway, I get this message; 

Invalid value for OPTIONS parameter PollMethod: must be 'GPSPositiveBasisNp1', 'GPSPositiveBasisNp1',
'MADSPositiveBasisNp1', or , 'MADSPositiveBasis2N'.


Strangely 'GPSPositiveBasis2N' isn't even in this list so I can't set it as the polling method, while 'GPSPositiveBasisNp1' is listed twice. How come? My Matlab version is 2008a.
