Generally speaking, unless you are an expert in a given field, it is
likely that a function exists somewhere that does your job, so start
looking for it before coding, or try asking on this list.

Anyway, this happened to me as well, exactly with the pwelch function,
but at that time I think pwelch was not still available, so I was
justified :)

>Worse, even when I 'know' a function exists, still difficult to find it!

Just install the "signal" package.

Have a look here, too: <http://octave.sourceforge.net/docs.html>, you'll
find pwelch there, together with much more.
