MATLAB Programming

MATLAB is a programming language developed by MathWorks. It started out as a matrix programming language where linear algebra programming was simple. It can be run both under interactive sessions and as a batch job. Alternatives to MATLAB exist including open source software packages.

Introduction

For the beginner just starting into MATLAB programming, a tutorial is available to write Hello World. Once Hello World, which is the simplest of programs, works the beginner can move on to explore the MATLAB workspace available for developing or running Matlab code.

Using the workspace the beginner can then learn to manipulate basic MATLAB Variables. For convenience Matlab allows the workspace to be saved and loaded using *.mat files.

Alternatives to MATLAB

Most MATLAB scripts and functions can be run in the open source program Octave. This program is freely available for most computing platforms. Also freely available is Julia language, and while it doesn't strive for full compatibility, see Julia for MATLAB Users.

Differences between Octave and MATLAB

The most important differences between Octave and MATLAB that anyone willing to use Octave instead of MATLAB should be aware of.
