Transfer Functions in Octave

This video tutorial explains how to define linear systems in Octave, focusing on transfer functions. It covers assigning names to variables, using commands to define transfer functions, and extracting information such as numerators, denominators, poles, and zeros. The tutorial also demonstrates how to extract state space matrices, providing a comprehensive guide to working with linear systems in Octave.

What is the primary focus of the video tutorial?
