[Eeglabnews] EEGLAB warning for users of Matlab 2013a

[Arnaud Delorme]

The MathWorks has implemented minor changes in Matlab 2013a with dramatic consequences as they could potentially break or corrupt the output of about 10% of EEGLAB functions.

EEGLAB graphic interface or command line users (all versions) should not upgrade to this version of Matlab until the issues have been fixed in EEGLAB (probably within a month). Details of some of the non backward compatible changes implemented by the Mathworks are described below.

The behavior of unique, union, intersect, setdiff, setxor, and ismember has changed.
	• If there are repeated elements in the input arrays, the functions unique, union, intersect, setdiff, and setxor return the index to the first occurrence of the repeated elements (or rows).
	• All index vectors returned by unique, union, intersect, setdiff, or setxor are column vectors.
