OctConf 2018

Tue, 09 Jan 2018 00:00:00 +0000

The Octave conference for 2018 will once again be held at CERN, near Geneva, Switzerland, from March 12 until March 15.

This four day event brings together many of Octave and Octave Forge developers, as well as members from the community. It is the ideal place to meet other Octave developers and users, to get help, and show Octave projects.

We are still working out the details of the program but there will be one day dedicated to workshops and coding projects, and another for an unconference. If there is a topic you would like to have discussed, or a workshop on a specific topic, please contact us.

While registration is free, there is a limited number of spaces. Please register at the CERN’s OctConf page
