I want to read from a binary data file, in the old matlab version of my script this is done by 

file=fread(data,'bit16');

which would be the equivalent thing in python ? i tried 

with open file(data, "rb") as f:
 d = np.fromfile(f, "<i2", count = 10000)

since the matlab documentation says that bitn is of the type signed integer with n bits

i tried different dtypes ( "<>i2", "int16") unfortunately this doesnt give me the rigth data.

    how did you write the data file? Commented Aug 12, 2013 at 12:57

    Just for whatever it's worth, np.fromfile('test.dat', np.int16) properly recovers data written from matlab with fwrite(fid, data, 'bit16') on my system. Commented Aug 12, 2013 at 13:47

You may try to use float16 data type associated with numpy.frombuffer that deals with the half precision floting point (bit16 in matlab). The type doc is here.
