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.

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 Alternatively, you can run Octave under Windows through Cygwin, which is similar to the GNU/Linux environment in. 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.

I am new to GNU Octave and I want to plot the function psi in the range of 0 : 2000: function y H(x) if (x > 0) y 1 else y 0 endif endfunction function y psi(s) t 200 phiabs 500 K 1000 n0 1000 y -n0 e. GNU Octave is also freely redistributable software.

it has built-in math functions and libraries.it has built-in support for complex numbers.Octave has the following common features with MATLAB − It is also used for numerical computations. GNU Octave is a high-level programming language like MATLAB and it is mostly compatible with MATLAB.
