Matlab files are being saved twice as large as necessary #72

Closed bgchristensen closed 7 years ago

bgchristensen commented 7 years ago

If I load a saved matlab data file, and then resave it, the size is reduced by approximately 0.5. How are we currently saving the matlab files? There may be a more efficient way of saving? It also just might be an issue with python itself (probably since we're using 32-bit)

Basically, I load a matlab data file of size 127 kB. I then resave the file and it will be of size 68 kB.

I've run one test and I saw a datafile getting down in size from 150 kB to 130 kB. Not as significant change.

We use scipy.io.savemat() to save the data. It appears that this method has a flag do_compression that is set to False by default. I'm changing this in the next commit.
