[edit] 1 WikiOctave

  • Allow execution of Octave from MediaWiki. Note that for security reasons, you should edit wikioctave.cgi to restrict execution from a list of hostnames and IP's.
  • Author: Brian Curtis (bcurtis3@gmu.edu) and Bob Weigel (rweigel@gmu.edu)

[edit] 2 VERSION:

  • 0.1.0.0 - 07/05/2007
  • 0.1.1.0 - 08/06/2007 -included minor file changes for compatibility with 2.9.9
  • 0.1.2.0 - 08/15/2007 -edited code for file structure to work universally (was my personal file structure)
  • 0.1.2.1 - 08/28/2007 -edited the octave command to include '-q' which removes unnecessary information from the output
  • 0.5.0.0 - 11/09/2007 -edited to allow restrictions by IP address and fixed a bug that caused the '+' to be read incorrectly.
