I will classify each one of these examples in terms of technical and programming difficulty.

I hope to write them in such a way they are easy to follow and to interact with them. Here you will find from simple to more complex examples. In its actual state of things, GNU Octave is a powerful, engineering-oriented, easy-to-learn tool. This language was created to mimic MATLAB, so most of the examples running under MATLAB's environment can effectively execute on GNU Octave. GNU Octave is a language and also free software for numerical computations. So I am written this page in both languages. I hope to have as readers English and Spanish speakers alike. A good idea is to create a directory called octave in your home directory and store all your Octave files in there.Examples files to learn GNU Octave / Ejemplos para aprender GNU Octave A number of example script files are provided and you should save these into a directory for later use. In the following section you will be shown a number of new statements that you can use to make your Octave code much more powerful. Note that the chdir('~/octave') command is necessary only if you are not already inside that directory when running Octave. For example, if I have a script called myscript.m in an octave directory, the following two commands will execute the script.Ĭhdir('~/octave') % This changes to the octave directory To run an existing script in Octave, you have to be in the same directory as the script file and type in the name of the file without the. m extension is used because MATLAB calls its script files M-files and Octave is based on MATLAB.) m extension so that Octave can recognise them. Such files are known as Octave script files. You might want to save your work or create code that can be reused (by yourself or somebody else). It is useful to be able to save Octave commands and return them later on. Here are some examples showing the input typed at the prompt and the output returned by Octave. Various constants are also pre-defined: pi, e (Euler's number), i and j (the imaginary number sqrt(-1)), inf (Infinity), NaN (Not a Number - resulting from undefined operations, such as Inf/Inf.)

natural and base 10 logarithms: log, log10.

inverse trigonometric functions: asin, acos, atan.

trigonometric functions : sin, cos, tan.

Many mathematical functions are available and have obvious names (with many of those similar to other programming languages). (multiplication), / (division), and ^ (exponentiation). To do simple arithmetic, use + (addition), - (subtraction), * The last line above is known as the Octave prompt and, much like the prompt in Linux, this is where you type Octave commands.
