read hdf5 files in matlab

To read HDF5 files in MATLAB, you can use the built-in h5read() function. Here is an example of how to use it:

main.m
% Open the HDF5 file
file = 'example.h5';
fid = H5F.open(file, 'H5F_ACC_RDONLY', 'H5P_DEFAULT');

% Get the dataset name
dset_name = '/group1/dataset1';

% Get the dataset id
dset_id = H5D.open(fid, dset_name);

% Read the dataset
data = H5D.read(dset_id);

% Close the dataset and file
H5D.close(dset_id);
H5F.close(fid);

% Inspect the data
disp(data);
355 chars
20 lines

In this example, we first open the HDF5 file using the H5F.open() function, which returns a file ID (fid). We then get the ID of the dataset we want to read (dset_id) using H5D.open(), and read the data using H5D.read(). Finally, we close the dataset and the file using H5D.close() and H5F.close(), respectively.

Note that the h5read() function can also be used to read HDF5 files in MATLAB, and provides a simpler interface for reading data. However, the above method provides more flexibility for handling complex datasets.
