mby3check

(Toolbox/mby3check.m in BrainStorm 2.0 (Alpha))


Function Synopsis

B = mby3check(A,WARN);

Help Text

MBY3CHECK - Check to see if matrix is m by 3 or 3 by m.
 function B = mby3check(A,WARN);
 Return matrix as 3 x M, with message to user if M is three also.
 Reject input if neither dimension is three.
 If optional WARN is zero, then no verbosity to user.
