If you want to execute a function defined in a file, just call the function like any other Octave function: foo(arg1, arg2); To execute a script from within Octave, just type its name without the .m extension. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments. --debug-d 7 If the call is from the command line, an anonymous function, or a script, the return value is an empty cell array. It may also be used as a batch-oriented language. 3. You can also specify the name of a file on the command line, and Octave will read and execute the commands from the named . --built-in-docstrings-file filename. FAQ - Octave Notice that in your example, as the function name matches the source file name, you will be calling the function inside the source and the last part of the code (i.e. Normally, high-level plot functions like plot or mesh call newplot to initialize the state of the current axes so that the next plot is drawn in a blank window with default property settings. Test your function with the input value of 4, 5 and 6. You run the script by typing the script name (without the file extension m) on the command line, causing all the expressions to be execued automatically as if they were written on the command line individually.

You can edit the script using any text editor, e.g. GNU Octave is an open-source alternative to MATLAB, a proprietary software and programming framework for conducting numerical mathematics and data analysis. By Barry O'Donovan. The following example is a simple-minded function using . Perl also provides a great file-open function to allow reading from a pipe (line 4), and we use the command-line unzip -c filename to feed each file in turn to Perl.
