charactors ("\n") -- it was broken on Windows, because opening the file in
text mode translated Windows newlines ("\r\n") to *nix style ones --
opening it in binary fixed that, but why use readlines at all? That's for
text -- use read. However, even better is to use fromfile(), which creates
an array form binary data in a file without puttin git in a string, first:
> matrix = np.fromfile(f, dtype=np.int16)
by the way -- be careful of endian issues here -- if you are moving data
among different machines. You could specify the endian-ness, for instance:
dt = numpy.dtype('<i2')
for a 16 bit little-endian integer.
