Importing HDF Data

Hierarchical Data Format (HDF) is a general-purpose, machine-independent standard for storing scientific data in files, developed by the National Center for Supercomputing Applications (NCSA). HDF-EOS is an extension of HDF developed by the National Aeronautics and Space Administration (NASA) for storage of data returned from the Earth Observing System (EOS).

HDF and HDF-EOS files can contain multidimensional numeric arrays or text data, called data sets, in HDF terminology. MATLAB provides three ways to import HDF or HDF-EOS data sets into the MATLAB workspace:

Using the HDF Import Tool
Describes a graphical user interface you can use to navigate through the data sets and metadata in an HDF file and import selected data sets from the file.

Using the MATLAB high-level import function
Describes how to use hdfread to import data from an HDF file.

Using the MATLAB low-level HDF functions
Describes how to use the MATLAB interface to the HDF and HDF-EOS application programming interfaces (APIs). For example, to import an HDF scientific data set, use the hdfsd function.

Note MATLAB supports Version 4.1r3 of the NCSA multifile APIs to HDF data. The multifile APIs replace the original NCSA APIs. MATLAB does not support HDF version 5.0, which is a completely new format and is not compatible with Version 4.1r3. To find more information about HDF, see Getting More Information About HDF.
