Math.NET Symbolics The 'Math.NET Symbolics' package of the C# opensource Math.NET project provides a computer algebra (CAS) framework covering symbolic and abstract areas of mathematics, in particular algbera and analysis/calculus. Symbolics Codename Yttrium First release expected in the 4th quarter 2005. Yttrium is an experimental computer algebra architecture, implementing ideas and concepts of formal hardware engineering and digital information engineering, looking at abstract math and algebra from a different, new angle. Yttrium is connected to the other new Math.NET packages like Numerics, PreciseNumerics and SignalProcessing, and thus takes direct advantage of the optimized numerical routines. Math.NET Symbolics: Yttrium Website Symbolics Classic Last release: June 2003 Classic basically is the whole old Math.NET project as it was in mid 2003. At that time computer algebra was the only part in the project - there were no specialized and isolated packages like Math.NET Numerics. To come around several limitations and problems due to the chosen architecture, the Yttrium project was brought into being, after going a long way round thinking about category theory. Yttrium will probably replace Classic in the medium-term. Nevertheless the Classic architecture still has some advantages and thus has a right to exist. Math.NET Classic Website
