High-level access functions make it easy to read and view data in an HDF5 file or write a variable from the MATLAB® workspace into an HDF5 file.
Low-level functions in the HDF5 library package provide direct access to the more than 300 functions in the HDF5 C library of the HDF Group. To create or write to non-numeric datasets or attributes, you must use the low-level functions.
To use the MATLAB low-level HDF5 functions, you must be familiar with HDF5 C API programming concepts, described at The HDF Group website.

Reading and writing data and metadata using the Hierarchical Data Format (HDF5) file format.
Hierarchical Data Format, Version 5, (HDF5) is a general-purpose, machine-independent standard for storing scientific data in files, developed by the National Center for Supercomputing Applications (NCSA).
MATLAB support for non-ASCII data and metadata in HDF5 files.
Write data to an HDF5 file in one process while you concurrently read from the file in one or more reader processes.
Access data stored across multiple HDF5 files as a single, unified HDF5 dataset.
