As mentioned in the previous section, Asir is a standard language
interface forRisa'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, Groebner 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 (see section
pari).
-
Distributed computation over UNIX
