For what?

If you mean that some scripts that are part of Octave depend on having
prefer_column_vectors set to 1, can you say which ones?  They should
be fixed to work no matter what the settings are.


Sorry for such a vague post, John (and other readers). The plplot demos do
not run with my configuration with prefer_column_vectors = 0
(debian sid running octave-plplot and latest 2.1 octave packages)
The problem is somewhere in plplot_octave.oct and so I'm not getting a trace.
I'm sure it's an easy fix but I don't have time today to track it down. 
x and y need to be column vectors.

If you set prefer_column_vectors = 1 and run plplot_octave_demo.m
everything works fine.

If you set prefer_column_vectors = 0 and run plplot_octave_demo.m
you see this:

Some demos print instructions, so keep this window visible.
