October 2025 Meeting: Octave Scientific Programming Language

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.
