Re: Plot Matrix in Octave

I'm at a loss as to how do to this in octave (well at least through
gnuplot), maybe someone more clever than I knows how to do this.

On the other hand, I'd suggest possibly looking into using octave to
automatically generate something like a .fig file for use in xfig.
The .fig files are simply ascii files that just list all the objects
and their associated properties.  I'd make the initial figure using
xfig but instead of numbers make some placeholders that you will
replace by the entries in the matrix in octave.

Depending on how flexible you need it to be, this might be too much
work, but this is the simplest way I know that you could automatically
generate those images.
