Web interface to Octave

Warning: this service is under construction!

Octave is a GNU scientific/numerical computing environment, which allows the user to perform typical numerical calculations, such as finding solutions to systems of nonlinear equations, scientific visualization, etc., using a very simple command line user interface to quite sophisticated libraries, such as LAPACK, QUADPACK, FFTW, etc. It is available for a variety of operating systems, including Linux and Windows.

Octave is quite often referred to as a MATLAB clone, because of its very high level of compatibility with this leading advanced numerical computing environment. Contrary to MATLAB, which is a commercial system, Octave is a free software.

Try Octave in your browser!

Here you may experiment with the basic functionality of Octave, version 2.9.9, accompanied with some of Octave-forge extensions. Learn more about this service!

If you are new to Octave, you may find it useful to read Octave's manual prior to using it.

All computation is performed on a computer at the Department of Mathematics, Warsaw University. Please do not submit codes that will run for a long time or take up a lot of memory. This service is intended for occasional, quick computations. If you like Octave, you should get your own copy - it is all free!

About this service

This web interface to Octave has been provided for individuals to experiment with Octave, i.e. to run some small, ad hoc calculations. Please do not launch jobs which use either a lot of CPU time, or consume a lot of memory, or filespace. All your activity on this page will be logged. If you don't like this policy, please get a standalone version of Octave.

Please send your comments or bug reports to knn@students.mimuw.edu.pl. We need your feedback.

Features

• Every user is granted a separate workspace (provided the browser accepts cookies). With the aid of load and save functions, you may keep some of your variables for later usage. Please do not abuse this feature!
• It is possible to make plots with the usual commands such as plot, mesh, etc. However only the first one is displayed in the browser.

Some of current restrictions

• For security, some functionality of the original Octave has been disabled in our installation.
• From time to time, all user workspaces are completely removed.
• Only the first plot is displayed in the browser.

History

This web page has been prepared and programmed in PHP by knn.mimuw.edu.pl. Our approach is based on the ideas from a similar web service, which contains a web interface to both R and Octave, written in CGI by Mai Zhou inspired by MJ Ray's Rcgi code.
