### 38.2 Using Packages

By default installed packages are not available from the Octave prompt, but it is possible to control this using the `pkg load` and `pkg unload` commands. The functions from a package can be added to the Octave path by typing

    pkg load package_name

where `package_name` is the name of the package to be added to the path.

In much the same way a package can be removed from the Octave path by typing

    pkg unload package_name
