+=====  FT_CHANUNIT =====
+Note that this reference documentation is identical to the help that is displayed in MATLAB when you type "help ft_chanunit".
+<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.
