I made  the following experiments. If I  run octave in a shell buffer,
then it seems that it takes all the columns. (I have 90).

If I reshape the  emacs  window, then it   seems that  octave  doesn't
change its idea of  the number of  columns  and it continues  to print
matrices as if the number of columns were 90.


On the other hand, if I use inferior-octave (from Kurt Hornik and jwe)
then octave takes the full  width of the window  (at the moment when I
launch the inferior-octave process). In  the following example I tried
with 140.

Do you use inferior-octave?
