There are a number of ways that you can contribute to help make Octave a better system. Perhaps the most important way to contribute is to write high-quality code for solving new problems, and to make your code freely available for others to use. See Contributing Guidelines, for detailed information on contributing new code.
If you find Octave useful, consider providing additional funding to continue its development. Even a modest amount of additional funding could make a significant difference in the amount of time that is available for development and support.
Donations supporting Octave development may be made on the web at https://my.fsf.org/donate/working-together/octave. These donations also help to support the Free Software Foundation
If you'd prefer to pay by check or money order, you can do so by sending a check to the FSF at the following address:
Free Software Foundation
51 Franklin Street, Suite 500
Boston, MA 02110-1335
If you pay by check, please be sure to write “GNU Octave” in the memo field of your check.
If you cannot provide funding or contribute code, you can still help make Octave better and more reliable by reporting any bugs you find and by offering suggestions for ways to improve Octave. See Trouble, for tips on how to write useful bug reports.
