 how to install Octave Forge Packages

• Start Octave and then open the build_packages.m file found in the src folder where Octave was installed.
• Run the script build_packages.m to build and install the packages.

 Installation is a one-time procedure. After installation packages must still be loaded in order to use them with the pkg load PACKAGENAME command.

Other packages are available from Octave-Forge.
