How can I install a package from Octave Forge?

How can I install a package from Octave Forge? I am using imresize function and I get this error

warning: the 'imresize' function belongs to the image package from Octave Forge which seems to not be installed in your system.

I tried doing this octave:1> pkg install -forge image-2.4.1.tar.gz. I got this error.

error: get_forge_pkg: package not found: "image-2.4.0.tar.gz". Maybe you meant "generate_html?" error: called from: error: /usr/share/octave/3.8.1/m/pkg/private/get_forge_pkg.m at line 73, column 9 error: /usr/share/octave/3.8.1/m/pkg/private/get_forge_download.m at line 26, column 12 error: /usr/share/octave/3.8.1/m/pkg/pkg.m at line 385, column 29

What are available packages for image processing in octave? How can I install them?

If you use -forge then only put the name and not the version.

pkg install -forge package_name # (not the version)

You can alternative do this:- This is permanent fix. In your terminal type

sudo apt-get install octave-<package_name_you_want> (eg-image)

and then in octave type

pkg load <pkg name>
