Can't write binary data to the standard output

[Akira Nishimura]

I'm using octave-2.0.13 and 2.0.14.

I want to write binary data to the standard output. The following
script is that I tested.

#!/usr/bin/octave -q

sf=11025;
t = (1:sf)/sf;
f = 1000;
sig = sin(2*pi*f*t);
fwrite(1, sig, 'int16');

This script outputs nothing, however, chainging fwrite to fprintf, e.g.

fprintf(1, '%g\n', sig);

correctly writes ascii data to the standard output.

How can I write binary data to the standard output?
