No, you are explicitly telling MATLAB that the file is big-endian when
you use 'b' (short for 'ieee-be') as the third argument to fopen(). In
Python, the file objects neither know nor care about integer formats;
they just give bytes. You have to use that knowledge when you convert
to a numpy object by picking the right dtype.

though it had an underlying truth."
