Answer 1

I had a look at this issue: https://github.com/h5py/h5py/issues/726. If you saved your mat file with -v7.3 option, you should generate the list of keys with (under Python 3.x):

import h5py
with h5py.File('test.mat', 'r') as file:
    print(list(file.keys()))

In order to access the variable a for instance, you have to use the same trick:

with h5py.File('test.mat', 'r') as file:
    a = list(file['a'])
