To read data or metadata from an HDF5 file, use the h5read function. As arguments, specify the name of the HDF5 file and the name of the dataset. (To read the value of an attribute, you must use h5readatt .)

The Hierarchical Data Format version 5 (HDF5), is an open source file format that supports large, complex, heterogeneous data. HDF5 uses a "file directory" like structure that allows you to organize data within the file in many different structured ways, as you might do with files on your computer.

data = h5read( filename , ds ) reads all the data from the dataset ds contained in the HDF5 file filename . data = h5read( filename , ds , start , count ) reads a subset of data from the dataset beginning at the location specified in start .

Opening local files myHDF5 supports opening local HDF5 files of any size, either by selecting them via a file picker from the Open HDF5 page, or by dragging and dropping them anywhere on the interface at any time. You can even select/drop multiple files at once.
