The C, FORTRAN and Java examples below point to the examples in the hdf5-examples github repository. Examples for older versions of HDF5 are handled by setting the appropriate USE_API_xxx definition. HDF5-1.6 examples are in a "16"-named subdirectory.
The Java examples are in the develop source code, and the Java Object package examples are in the HDFView source. Please note that you must comment out the "package" statement at the top when downloading a Java Object example individually.
The MATLAB and Python examples were generously provided by a user and are not tested.
Languages are C, Fortran, Java (JHI5), Java Object Package, Python (High Level), and Python (Low Level APIs).
