Dayton Linux Users Group October Meeting: Octave Scientific Programming Language
Details
Presentations/Topics:
GNU Octave is a free, open source alternative to the commercial software ‘Matlab’. It provides an interpreted programming language for numerical computations. It is highly compatible (~95%) with Matlab syntax and functions. With a BSD-style license, it works on Linux, macOS & Windows.
JMB will briefly share his past experience in using Octave for very complex calculations of a gas ejector, replicating a doctoral thesis that used Matlab. Octave was proven to be equally capable in reproducing the same results / graphs. Octave was also used by the presenter for real-time thermodynamic mass, energy & heat flow calculations for a recreational vehicle (RV) refrigerator system, combining it with ‘CoolProp’ (the open source alternative to the NIST ‘RefProp’) library for thermodynamic properties of fluids. These refrigerators are usually NH3 absorption systems with no moving parts, thus require very complex chemical process calculations.
The presenter will show how to install and use Octave, using simple examples including plotting graphs; ending hopefully in a live demo of a working Octave setup.
We’ll also talk about the Installfest we held on October 4th, the upcoming OLF conference, and the just-opened TechFest registrations.
As always, we’ll have discussion time for Linux and Open Source news, projects you’re working on, and questions for the rest of the group.
Where:
Wright State University
Russ Engineering Center, Room 302
(Room right across the hall from the elevators.)
If we can arrange it, we will also have an online presence via the Zoom web conferencing service.
If joining a meeting from a Windows PC, the Zoom client will automatically download and attempt to install. For those using Linux, you can download the free (not Free) Zoom client from this page. It’s available for a variety of distributions.
For those attending in person, we will most likely adjourn to Milano’s afterward for food and socializing.

The Dayton Linux Users Group, a Special Interest Group (SIG) of the Dayton Microcomputer Association, meets the 3rd Thursday of the month Online.
At our monthly meetings, we may have one or more presentation topics planned, or we simply discuss news and projects of interest to our members. (We’re working on planning presentations for more of our meetings, and could use some volunteers — hint, hint!). Our attendees include anyone from experienced Linux system administrators to those who have been hearing about Linux and want to learn more.
