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 HDF5-1.14 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).
