Hello everyone,
I have opened a .h5 file with MATLAB and want to change a dataset, which datatype ist H5T_COMPOUND (struct). I have written a new struct data (same struct, just one field's value changed), do you know how to write it into h5 file? Thank you!
Best Regards
Xiao

I adapted the code from https://support.hdfgroup.org/HDF5/examples/api18-m.html and created a file exchange function struct2hdf5 for everyone to use: https://www.mathworks.com/matlabcentral/fileexchange/106470-struct2hdf5

‘hdf5write' can be used to write data to a file in ‘.h5’ format.
For more information on how to use ‘hdf5write’ refer to the following link

If the Matlab support of HDF5 has not been updated in the most recent years there is no high level support for writing compound data to h5-files.
I found only this in the File Exchange Edit_struct_hdf5 by Renato Medeiros. It might be useful to you.
It can be done with the low level HFD5 functions, but I find it a bit tricky, YMMV. Did you study the low level Matlab samples at https://support.hdfgroup.org/HDF5/examples/api18-m.html, especially
- Read / Write Compound Datatypes (Dataset) h5ex_t_cmpd.m and
- Read / Write Compound Datatypes (Attribute) h5ex_t_cmpdatt.m
