Thank you, Isak. This spreadsheet interface greatly helps me.
I have now installed octave-io from distro repository. I am running
octave via:
octave --force-gui
How does one load octave-io, please?
when you do
pkg list
you should see a list of all the pkgs that have been installed'
If the is a * next to the pkg name then it is also loaded.
to load a pkg type
pkg load "pkgname"
pkgname is the name in the list
Thank You,
