Sage is a free open-source mathematics software system. It’s a GPL alternative to commercial software such as Magma, Maple, Mathematica and MATLAB. Sage is a research-grade tool, cited in nearly 100 academic research articles (with dozens more in press).
I’ve written a book to help engineers, scientists, and students get started with Sage. It’s available in print and e-book formats. Please check it out!
I am aware that there are a number of issues with the code bundle that is available on the Packt site, but I have not been able to get the publisher to replace it.
Since the book was published, a number of minor errors have been discovered. Sage has also evolved, which in some cases has changed the functionality of the examples. If you have specific problems to report, please email them to me, and I will add errata to this page.
