Creating a .mat file of v7.3 in python
<p>I need to perform multiplication involving 60000X70000 matrix either in python or matlab. I have a 16GB RAM and am able to load each row of the matrix easily (which is what I require). I am able to create the matrix as a whole in python but not in matlab. 
Is there anyway I can save the array as .mat file of v7.3 using h5py or scipy so that I can load each row separately? </p>
