How To Download Octave
Octave is free and can be downloaded on Octave website gnu.org/software/octave/GNU . OCTAVE is a high–level language designed for scientific computations. It is most compatible with MATLAB in speed and syntax (to some extent).
Lesson 1.1: Octave Tutotial - Introduction
Octave is a software featuring a high-level programming language. Octave helps solve linear and nonlinear problems. Octave has the command windows and editor section which can be executed for coding. Simple exercise:
LESSON 1.2 – HELP FUNCTION, DISP FUNCTION, INPUT FUNCTION
On Command windows = type help disp. Octave will explain in detail how the help function can be used, disp =("Hello world!), Round, floor, input =("Hello world!")
LESSON 2.1 –OCTAVE TUTORIAL (MATLAB): COMPLEX NUMBERS, TRIGONOMETRY, SQUARE ROOT
Complex (2, 5); - 2 + 5i; Example: - (2+5i)*(2-5i); √(sin〖(30)^2+cos〖(30)^2 〗) = sqrt ((sin(30)^2)+(cos(30)^2) )
LESSON 2.2 OCTAVE TUTORIAL (MATLAB): ROW VECTORS, ARRAYS, ADDITION OF VECTORS MATRIX
Creating Row vectors use spacing () or commas (,); Creating Column vectors use semicolon (;) or transpose sign (‘); multirow matrices; Display function; To multiply element by element. 2*M

Transfer Function - Process Control Example 1 using Octave
Consider A Laplace transform of function G(t) given by
G(s)=Q(s)/P(s) =(4s^2-4s+24)/(2s^3-4s^2-2s+4)
1. Determine the function G(t) using Octave. First use Octave to determine the roots (hint: create row vectors)
G(s)=Q(s)/P(s) =(4s^2-4s-24)/(2s^3-4s^2-2s+4)=5.333/(s-2)+2.6667/(s+1)-6/(s-1)
