Both CDF and netCDF are much easier to learn and use than HDF and CDF
is a superset of netCDF, not the other way around. Both IDL and
MatLab have a built-in support for CDF, and there's a suite of IDL
routines with which you can manipulate CDF files (e.g. read, write,
plot, etc.) at http://spdf.gsfc.nasa.gov/CDAWlib.html.

There's a data format translator at http://translators.gsfc.nasa.gov
that allows users to translate files between CDF, netCDF, and FITS.
