Not a Matlab solution, but if you have access to NCO ( http://nco.sourceforge.net/), issued from a terminal window:
ncks -x -v varname in.nc out.nc
or within Matlab:
system('ncks -x -v varname in.nc out.nc')

"Attributes are more dynamic than variables or dimensions; they can be deleted and have their type, length, and values changed after they are created, whereas the netCDF interface provides no way to delete a variable or to change its type or shape." - http://www.unidata.ucar.edu/software/netcdf/docs/netcdf.html
The only way would be to copy over everything, but the variable you want to delete, to a new file.
