Hi,
I just pushed a modification to load_csv_file_data.m that should make it work noticeably faster on Matlab.
Though I have tested it a bit, in order to avoid breaking anyone's code, I pushed it onto a branch called matlabLoadCSV.
If you have a free moment, please test it. Once you've had a chance to test it, I'll merge it onto master (probably on Monday).
Best, Houtan
