When files are saved in -v7.3 .mat file which is hdf5 format, the load function works very slow compared to h5read. Are there better optimized load functions for .hdf5 mat files?

Hi Suresh,
Version 7.3 .mat files use a HDF5 storage format which may require some overhead. You can read more about differences between .mat file formats in our documentation:
We can try saving the files in a different .mat file version using the following command:
>>save('mymatfile.mat','-v7');
We can also use the "matfile" function to load or save variables. More information about this function can be found here:
Thanks!
