A computer algebra system: Risa/Asir? (English) Zbl 1027.68152
Joswig, Michael (ed.) et al., Algebra, geometry, and software systems. Berlin: Springer. 147-162 (2003).
Risa/Asir is a tool for performing various computations in mathematics and engineering applications, a computer algebra system for efficient algebraic computations. It is also designed to be a platform for parallel and distributed computation under the Open $$XM$$ (open message eXchange for Mathematics) protocol. Open $$XM$$ defines client-server communication between mathematical software systems and Risa/Asir is one of main components in the Open $$XM$$ package. The source code of Risa/Asir is completely open and it is easy to modify the source code or to add new functions. In this paper, the author gives an overview of Risa/Asir, explains its functions and implemented algorithms with their performances, the Open $$XM$$ API and the way to built-in functions.
