[OctDev] quiver does not seem to work under debian

[V. <gae...@en...>]

  Hello,

  I cannot have quiver work under my Linux boxs (debian, sarge and
woody), however I have no problems under Windows/cygwin. I do not really
understand this issue, it may be an problem with gnuplot.

  Here is a minimal exemple :

GNU Octave, version 2.1.64 (i386-pc-linux-gnu).
[snip]
octave:1> [X,Y]=3Dmeshgrid(1:4);
octave:2> quiver(X,Y,X,Y);
octave:3>          line 0: Not enough columns for this style


   The error message is a gnuplot error. I investigated a bit further :
octave:3> M=3D[X(:),Y(:),X(:),Y(:)];
octave:4> gplot M w v
         line 0: Not enough columns for this style

   So I tried to see if the problem was with gnuplot :
octave:5> save -ascii 'quiver.dat' M
octave:6> quit

   And under gnuplot :

        G N U P L O T
        Version 4.0 patchlevel 0

        System: Linux 2.6.5

[snip]
gnuplot> plot 'quiver.dat' using 1:2:3:4 w vec

  That works fine.

   I am sorry I am completely new to octave so I am having difficulties
diagnostic where the problem is.

   I am working around this problem by saving a data file, but it is a
bit of a same I cannot have quiver work under an out of the box debian
system. What I am doing wrong ?

   Regards,
