SAL Home MATH Computer Algebra System


Risa/Asir an experimental computer algebra system developed at FUJITSU LABORATORIES LIMITED, is publicly available in binary form. It provides a programming system Asir with several subroutine libraries that can also be used as parts of other programs. Its programming system Asir has a C-like language, also called `Asir,' its interpreter and a dbx-like source-line debugger. The source line debugger is very helpful and may be indispensable for those who want to implement algorithms for algebraic computation.
Risa/Asir provides strong facilities for polynomial problem solving: factoring polynomials over various coefficient domains, and Groebner basis and related ideal computations. On the top of such polynomial tools, primary/prime decomposition of polynomial ideals, direct and concrete computation of Galois groups of polynimials, and radical representation of polynomial roots are implemented.
