Yttrium Diagramming

There was quite a huge check-in lately on the yttrium source code repository . I've been refactoring the yttrium code base to a new microkernel based architecture (motivation: getting rid of cyclic dependencies and the high degree of complexity). The most striking change is the number of assemblies...

PowerShell for Math.NET

I think it would be really interesting to propagate the new MS PowerShell as a new interface for Math.NET, especially for the Yttrium project. Yttrium already provides very simple script support, but PowerShell has so much more to offer. I think about writing some PowerShell cmdlets and functions, and...

Yttrium Insights, part 4: Core Components

To ensure we understand the same thing when talking about signals, ports and architectures in the yttrium context, I try to give a short high-level introduction in this article. Mathematical Expressions in Yttrium In a classical computer algebra system (CAS), expressions are organized in trees. For example...

Yttrium Insights, part 3: Yttrium Packages

One of the more important points in the beginnings of Math.NET Symbolics was extensibility and a dynamic behaviour. You should be able to define your own operations and data structures . To put this to an extreme, the framework core should be seperated and independent from any data types and operations...

Yttrium Insights, part 2: In and Out - The System Builder

A recent addition to the Yttrium framework is the system builder. The idea is to define a "command based" description of a math system ( MathSystem class) to seperate the construction of such a system from the system itself. In incorporates ideas from the builder design pattern . The central point is...

Yttrium Insights, part 1: Traversing a Math System

Yttrium models basically are arbitrary bibartite directed graphs with ports on one and signals (and buses) on the other side. Signals connect ports with each other in any way, including loops and cycles. The screenshot above shows two cyclic models with three ports each (divide, add, multiply - click...

Yttrium Insights, part 0: Intro

First of all, sorry for the long absence. Time...... I've spent a lot of thoughts on the new Yttrium design. It's a kind of an architecural playground to try out new ideas. I think I found several interesting approaches to solve very specific problems, although some of them are slightly complex - I hope...

Internetworking and Computer Algebra

Yttrium has always been an interdisciplinary fusion of several different concepts. After ideas from VLSI and VHDL, concepts from communication networks and Internetworking are coming along now, too: Yttrium signals carry "values" which are characterized by structures (classes derived from ValueStructure...

Yttrium Parser: Grammar Preview

Like Math.NET Classic, Yttrium will provide a parser to construct a system from an infix string. During the last two days I've begun writing the parser, based on the new more systematic parsing infrastructure introduced in (never released) Symbolics Classic v0.19. Porting to Yttrium has shown to be astonishingly...

Working with Yttrium

The intention "Make the simple things simple and the hard things possible" of the Designing Reusable Class Libraries PDC05 presentation is continuously realized in Yttrium (although some other guidelines are still violated - one of the reasons why I still have not published any code yet). At least many...
