First off, if the code below is usrp_rx_cfile.py, just say so, don't
post it. I'm assuming that it is, and thus is a known quantity.
The easiest way to get complex binary samples into octave (or
matlab) is to use the existing tools.
Set your matlab/octave path so that it'll look in gnuradio-core/src/utils
Then use:
>>> data = read_complex_binary('myfile.dat', 1e6);
which will read the first million complex samples in.
