I just installed yapso on a fairly recent CVS snapshot of octave on ubuntu edgy eft, but I couldn't get it to work. If I run (as an example)
"test_sombrero" I get:
  "error: `surf' undefined near line 8 column 4"

So, I looked at the directory where the package is installed, and the only oct file I see is "yfunction.oct". Is that correct? Shouldnøt I also have ""ysurf.oct" (and more)?

Hi all,

I wrote some plotting routines to visualize ocean model results (although it 
can be used for other
applications). I wanted to share it because it might be useful for others as 
well. I called this
package Yapso, Yet Another Plotting System for Octave. It is intended to be 
compatible with Matlab
plotting commands. Yapso is based on the OpenGL libraries and it uses 
(currently) the GLUT toolkit
(freeglut or openglut). Yapso is loaded dynamically in Octave as oct-functions 
which allows a tight
integration in Octave.

What I missed from existing graphics packages was offscreen rendering (matlab's 
-nodisplay option)
which allows you to create plots from a cronjob or from a webserver cgi.

You can download it from and demos can be found at

Yapso is bundled as an octave package which is installed by "pkg install 

Have fun!
