Finally, it demonstrates how to optimize your code and link GNU Octave with C and C++ code enabling you to solve even the most computationally demanding tasks. It then goes on to show you how to write new functionality into GNU Octave and how to make a toolbox package to solve your specific problem. The book starts by introducing you to work variables like vectors and matrices, demonstrating how to perform simple arithmetic operations on these objects before explaining how to use some of the simple functionality that comes with GNU Octave, including plotting. This practical guide takes you from the basics where you are introduced to the interpreter to a more advanced level where you will learn how to build your own specialized and highly optimized GNU Octave toolbox package. Using real-world examples the GNU Octave Beginner's Guide will take you through the most important aspects of GNU Octave. It's easy to learn GNU Octave, with the GNU Octave Beginner's Guide to hand. The book is based on numerous concrete examples and at the end of each chapter you will find exercises to test your knowledge. The GNU Octave Beginner's Guide gives you an introduction that enables you to solve and analyze complicated numerical problems. With GNU Octave you have a highly flexible tool that can solve a vast number of such different problems as complex statistical analysis and dynamical system studies. Today, scientific computing and data analysis play an integral part in most scientific disciplines ranging from mathematics and biology to imaging processing and finance.

If you install Octave you can copy and paste these commands to see the full output from each line. Often I'll explain output in the % comments, but generally I have saved space by not showing any output lines. Here I go through some commands - roughly in the order I saw them in the online machine learning course.

It works on all platforms, although on windows you will need to install it with Cygwin. Octave is an excellent language to prototype machine learning.
Most of them I actually saw in an excellent online machine learning course which is referenced and acknowledged properly below, and was my reason for learning Octave.
This page is my own "cheat sheet" where I list out most of the commands I'll need.

The language is very similar to and *mostly* comaptible with MATLAB - but unlike Matlab is free and open source under a GNU General Public License. It provides its own command line interface for solving linear and nonlinear problems and plotting graphs. GNU Octave is a high-level programming language, primarily intended for numerical computations, and very useful for matrix operations.
