I agree. I think patch #8607 implements some of the functions in the "high-level functions" interface. It does not address the "low-level functions" set at all.

The configure script checks for HDF5 for the -hdf5 option to the load and save functions.

There is a patch for more general HDF5 support here:

https://savannah.gnu.org/patch/?func=detailitem&item_id=8607

but I don't know whether that patch supports the package notation that you note is missing.

I don't know whether we should keep this report open.  The issue is much larger than just "H5T.copy".  It is really a (quite large) feature request.

In Matlab the following command is accepted:

>> b = H5T.copy('H5T_NATIVE_FLOAT')

b =
    50331962

In octave it results in a syntax error:

>> b = H5T.copy('H5T_NATIVE_FLOAT')

error: 'H5T' undefined near line 1 column 5

It is something to do with hd5 (https://mathworks.com/help/matlab/low-level-functions.html).

The configure script found the library,

HDF5 libraries:                -lhdf5

but I guess there is no interface to the functions. Just wondering if this is something that is planned for Octave?
