Hi @Snyder
To modify values within an HDF5 file in MATLAB while maintaining its structure, you can use the "h5read" and "h5write" functions.
- Read the existing datasets using "h5read".
- Make the necessary changes to the datasets in MATLAB.
- Update the datasets in the HDF5 file using "h5write".
Refer to the following MathWorks documentation links for more information on "h5read" and "h5write" respectively:
