Re: [Discuss-gnuradio] viewing data in octave

[George Nychis]

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.
