function c = demean(c)
   
   % DEMEAN removes the mean of each trace.
   %
   % C = DEMEAN(C) removes the DC offset from each trace. In most cases it is
   % unnecessary to call this function directly. By default, all traces are
   % demeaned and detrended when they are loaded into a correlation object.
   % This is one of the assumptions of the correlation toolbox.
