Description:

You can find the list of packages by clicking on the Packages link at the top. To install a package, use the pkg command from the Octave prompt by typing: pkg install -forge package_name, where package_name is the name of the package you want to install. New lists of requested general contributions and of packages with new mainainers sought.2017-08-10 Function database can handle nested namespaces and classes under namespaces.2017-05-28 Changed template root level Makefile. If it has to install the package, this installation now goes into an extra directory and doesn't interfere with the installed packages seen in a normal Octave session.2017-03-29 packages assigned to groups community packages and external packages2017-03-13 A web interface which checks for symbol duplications (function names, class basenames, namespace names) over Octave Forge packages and Octave is provided.
