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!
