Where is the gnu octave executable
For example, we can look at all the files in the current directory to list only those whose extension is ".m". Of course, we can use GNU Octave to do more useful things. If we don't want to type "octave" in order to run the script, we can put this line:Īt the start (be sure to use the correct path on your system), and do chmod +x first.m to make it executable. The GNU Octave program printed out "55", just like we expected. If we save this file as first.m, we can run it from the command line. It then uses the disp function to display the result, which should be 55. In this example, we create a variable called a, which stores the result of the sum of all natural numbers between 1 and 10. You can use any text editor to create this file - Emacs, Vim, Gedit, or whatever your favorite is. GNU Octave scripts can be named anything but conventionally end with ".m".

This compatibility could enable you to suggest users of non-free interpreters of MATLAB/GNU Octave languages to experiment free software alternatives.Īpart from directly using the interactive interpreter, one could also invoke GNU Octave by using a text editor to write a file and then passing it to the octave program. The GNU Octave programming language is largely compatible with the MATLAB language so that most of the commands and scripts you can write for GNU Octave can also be used as MATLAB language commands or scripts, and vice-versa. Instead of explicitly iterating over the array, it is possible to let GNU Octave take care of the details: octave:3> '* Iterating the sum by showing the partial cumulate sums is also straightforward:Ī multiplication table can be generated by multiplying the first ten natural numbers each other, in all possible combinations. Summing the first ten natural numbers can be easily done with the command sum : The text " octave:1>" is the prompt of the GNU Octave interpreter, ready to read your first (" :1>") command.Ī sequence (an array) with the first ten natural numbers can be generated by typing 1:10 (meaning: from 1 to 10): octave:1> 1:10 The easiest way to experiment with it is to open its interactive intepreter: GNU Octave is included by default with most GNU/Linux distributions.

) but a collection ( arrays) of such elements on which an activity is to be applied element by element without the need to explicitly tell GNU Octave to do so. However, GNU Octave language belongs to the category of array-programming oriented languages and this can be summarized by saying that the typical elementary object within GNU Octave is not a single element (a certain file, line, number. This is not new to experienced command-line users and many other languages allow such a convenient conciseness. The peculiarity of GNU Octave is that it enables sequences of activities to be performed as if they were a single activity to be silently iterated over all elements of a given set of things (e.g. GNU Octave is both a programming language and a command-line language interpreter.
