with the HDF5 specs.

Why is this against the HDF5 spec?

Because when I save the data as HDF5 file and then zip the file then it won't be a HDF5 file anymore. It would be a zip file.

Actually, zipping a HDF5 file would be not a good solution, because HDF5 already supports compressing of individual variables, including chunking and shuffling, hence more efficient. All of them is implemented in the HDF5 library - all we need is to activate it.

Do you know how to do it in Octave?
