[Pkg-octave-devel] Bug#454157: octave2.1-forge: some patches

[Francesco Potorti`]

Package: octave2.1-forge
Version: 2006.03.17+dfsg1-3
Severity: minor
File: /usr/share/octave/site/api-v13/m/octave2.1-forge/signal/pwelch.m

This patch allows using the default argment [] for the last three args
range, units, trend and corrects some documentation bugs.

The last hunk of the patch corrects a problem whereas title, axis labels
and grid are deleted just after the plot is shown.
