A Java API ...
... for doing Calculus with Hypercomplex Numbers
© Markus Maute (2006-2015)
The API is not publicly available yet, but is already running quite robustly. To get a flavour of what it can do, you can have a look at the Javadoc.
If you are interested in using the API for scientific or commercial purposes, please contact me.
More on hypercomplex numbers can be found in the autor's Web Notebook ...
