RE: load hdf5 file that contains compound datatype for a dataset

[Lucas Salvador]

Hi Mike,

Thank you very much for your fast answer. I could load hdf5 file partially 
using 

data_results = load('-hdf5','-force',hdf5_file,'Results');

where Results is a dataset. I only have the problem with another dataset which 
is of compound type. I would like to try any tool that can load the whole file 
such as your patch or h5util, yet I am a newbie with octave and don't know 
exactly how to install a .cset file (such as in the forum thread you sent) 
without building the whole software. 

Is there a function .m available (such as the 'load' function of octave) that I 
could use as a separate function without any installation of package build?

Thanks!
Best regards,
Lucas

Octave's load function does not load HDF5 files, so this error message is 
correct, the file is not in a format recognized by Octave.

There is a h5read function in development that will read data from HDF5 data 
files, but it is not part of Octave yet. Do you have the time and interest to 
build Octave yourself and test this new function?
