hdf5info — Legacy alias for HDF5 metadata traversal.

hdf5info(filename) and hdf5info(filename, location) are legacy compatibility names for h5info.

Syntax

hdf5info(filename)

How hdf5info works

  • Returns the same metadata structure as h5info.
  • Traversal is recursive for groups.

Example

Inspect a legacy HDF5 file

info = hdf5info('measurements.h5');

Using hdf5info with coding agents

Open a RunMat example with live inputs, then ask the agent to explain how hdf5info changes the result.

Run a small hdf5info example, explain the result, then change one input and compare the output.
