Ah, I got the impression you were looking for a quick way to read the 
files into MatLab.

They're native-binary floating-point data, either "float" or "complex 
float".

In Python there's a plethora of ways of handling that, but numpy would 
be the best bet, and I see that Josh
  has already recommended numpy.fromfile.

For significant storage-size and performance reasons, the "file sink" 
blocks in Gnu Radio store their data in the native
  floating-point format.  Although for low-speed data, one might 
consider Josh' new python-blocks stuff, which could
  do conversions on-the-fly into a number of different formats, 
including printable ones.
