Sure, i would make sure that LOADPATH is actually correct. You want to
make sure it actually has the GNU Radio octave scripts in it.

Do:
ls -l ~/gr-build/gnuradio-core/src/utils

and you should see something like:
total 136
-rw-r–r-- 1 gnychis gnychis 1491 2007-06-18 09:54 cool.m
-rw-r–r-- 1 gnychis gnychis 1254 2007-06-18 09:54 db_width.m
-rw-r–r-- 1 gnychis gnychis 1337 2007-06-18 09:54 filter_tools.m

If the path is incorrect, you will get an error like:
ls: /home/gnychis/gr-build/gnuradio-core/src/utils: No such file or
directory

Basically you want to set the loadpath correctly to point to a place
where you keep the GNU Radio source code.

Different versions of octave require very different formats for the
loadpath. The only thing that works on my version of octave is the
following format:

addpath("/home/matt/octave-bin")
addpath("/home/matt/gnuradio/gnuradio-core/src/utils")

Matt

Thank you guys, it worked
