Asir

An open source general computer algebra system

Asir is a standard language interface for Risa’s algebraic engine. Usually, it is provided as an executable file named asir. Main features supported for the current version of Asir is as follows.

A C-like programming language
Arithmetic operations (addition, subtraction, multiplication and division) on numbers, polynomials and rational expressions
Operations on vectors and matrices
List processing operations at the minimum
Several Built-in functions (factorization, GCD computation, Gröbner basis computation etc.)
Useful user defined functions (e.g., factorization over algebraic number fields)
A dbx-like debugger
Plotting of implicit functions
Numerical evaluation of mathematical expressions including elementary transcendental functions at arbitrary precision. This feature is in force only if PARI system installed.
Distributed computation over UNIX
