2011-12-09 Thread Tom Diethe
I have files stored using Matlab's sparse format (HDF5, csc I believe), and I'm trying to use Pytables to operate on them directly, but haven't succeeded yet. Using h5py I can do the following: # Method 1: uses h5py (WORKS) f1 = h5py.File(fname) data = f1['M']['data] ir = f1['M]['ir'] jc = f1['M']
