HDF5 Documentation
0 likes563 views
The HDF5 documentation aims to cater to various user needs, including data users, application developers, and library developers, by providing relevant guides, tools, and support. It emphasizes the importance of user feedback for improving documentation and offers links to resources for C, Fortran, C++, and Java interfaces. Additionally, it includes information on pre-release snapshots and the collaborative nature of documentation creation involving developers.
