TO Phenyo Moletsane 

Please always keep CCing help-octave list.

>> Also, can octave be used for big data? 

To my knowldge, Octave can han handle hdf format.

Netcdf package is available on octave-forge.
If you are using octave 4.2.1 on windows,
netcdf and database packages are pre-installed.

You should import package bofore use e.g. pkg load netcdf.

64 bit binary can handle ~4GB arrays.

If you want use large arrays, exeperimetal build is available via

Please add much information for big data treatment on GNU Octave.
