Low-Level Functions for HDF4 Files
MATLAB® provides functions in three packages for accessing the HDF4 SD, GD, and SW interfaces. In addition, interface functions allow direct access to other HDF4 APIs. To use these functions, you must be familiar with the HDF library.
MATLAB supports HDF4 version 4.2.15.

Examples and How To
- Map HDF4 to MATLAB Syntax
Each HDF4 API includes many individual routines that you use to read data from files, write data to files, and perform other related functions.
