 +<​html><​pre>​
 +  <a href=/​reference/​ft_chanunit><​font color=green>​FT_CHANUNIT</​font></​a>​ is a helper function that tries to determine the physical
 +  units of each channel. In case the type of channel is not detected, it
 +  will return '​unknown'​ for that channel.
 + 
 +  Use as
 +    unit = ft_chanunit(hdr)
 +  or as
 +    unit = ft_chanunit(hdr,​ desired)
 + 
 +  If the desired unit is not specified as second input argument, this
 +  function returns a Nchan*1 cell array with a string describing the
 +  physical units of each channel, or '​unknown'​ if those cannot be
 +  determined.
 + 
 +  If the desired unit is specified as second input argument, this function
 +  returns a Nchan*1 boolean vector with "​true"​ for the channels that match
 +  the desired physical units and "​false"​ for the ones that do not match.
 + 
 +  The specification of the channel units depends on the acquisition system,
 +  for example the neuromag306 system includes channel with the following
 +  units: uV, T and T/cm.
