Re: Yet Another Plotting System for Octave

[Marius Schamschula]

Hi all,

I tried installing yapso on my Mac OS X 10.4 box with octave 2.9.9. I've run into a problem with the "pkg install" mechanism:

octave:1> pkg install yapso-0.2.1.tar.gz

warning: You have not defined an installation prefix, so the following will be used: /Users/marius/octave/

tar: yapso-0.2.1.tar.gz: Cannot open: No such file or directory

tar: Error is not recoverable: exiting now

warning: implicit conversion from scalar to string

error: tar: tar exited with status =

1) How do I specify the installation prefix? yapso should be globally accessible, not in my personal home directory.

2) Why is tar failing to find the tarball? I invoked octave in the download directory.

octave:1> ls

yapso-0.2.1             yapso-0.2.1.tar.gz

I manually extracted the archive, and it is complete.

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 http://yapso.sourceforge.net/ and demos can be found at

http://yapso.sourceforge.net/demo.html.

Yapso is bundled as an octave package which is installed by "pkg install yapso-0.2.1.tar.gz".

Have fun!
