Code

Here you will find code to generate data, reproduce results, or simply use the methods that we invent or just simply use. While the code is believed to compute what it is claimed to compute, the code is being made available as a convenience, without guarantee. Some of the code authors are interested in comments and bug reports. These are noted in the folder containing the link for the download.
