Let's try another one! (Remember, just type: "contourf(peaks)" at the prompt) Cool, right!? Don't worry if you don't know much about graphing or plotting stuff, we just wanted to make sure this worked. You should see a 3-D surface plot graphical window come up. Get back into Octave by typing octave in your console, then at the prompt, type the following below (don't type octave:1>, that's just part of the program): Let's test out Octave and do something cool! Let's try making some plots to see what Octave is capable of.

Octave is availabe for most platforms (Windows, Mac OS X, Linux). We will assume that you haven't done very much programming, and we will refer to GNU Octave as just "Octave".

MATLAB liscenses typically cost around $50 if you are a student or $150 if you are a home user, so if you don't want to spend money but still be able to do scientific computing and data analysis, read on! What to Expect from this Tutorial One key difference to note right off the bat is unlike MATLAB, GNU Octave is free, so it makes for a great alternative. In fact, it's so similar that some call GNU Octave a MATLAB "clone" because most MATLAB scripts can be ran by GNU Octave. In the broad sense, it is a numerical computing environment and programming language similar to MATLAB. GNU Octave is a high-level, multi-functional scientific tool used for numerical analysis.

This tutorial has tried to give both type of examples where they differed in their syntax.Ĭonsider following example where MATLAB and Octave make use of different functions to get the area of a curve: f(x) = x 2 cos(x) for −4 ≤ x ≤ 9.A tutorial for those wanting to learn GNU Octave. Though all the core functionality of MATLAB is available in Octave, there are some functionality for example, Differential & Integration Calculus, which does not match exactly in both the languages. When you run the file, MATLAB displays the following 3-D map − Non-compatible Examples Create a script file and type the following code − This example creates a 3D surface map for the function g = xe -(x 2 + y 2). Let's try following example in MATLAB and Octave which produces same result without any syntax changes − Compatible ExamplesĪlmost all the examples covered in this tutorial are compatible with MATLAB as well as Octave. If you are looking for a tutorial on Octave, then kindly go through this tutorial from beginning which covers both MATLAB as well as Octave. Most MATLAB programs run in Octave, but some of the Octave programs may not run in MATLAB because, Octave allows some syntax that MATLAB does not.įor example, MATLAB supports single quotes only, but Octave supports both single and double quotes for defining strings.
