Simple object oriented designed computer algebra system

摘要

Computer Algebra System (CAS) is a software program that facilitates symbolic mathematics. The core functionality of a typical CAS is manipulation of mathematical expressions in symbolic forms. The expressions manipulated by CAS normally include polynomials in multiple variables, standard trigonometric and exponential functions, various special functions for example gamma, zeta, Bessel, etc. and also arbitrary functions like derivatives, integrals, sums, and products of expressions. Our implementation of a CAS tool provides an object oriented design framework. The system is portable to other platforms and highly scalable. The other key features include a very simple and interactive user GUI support for a formula editor, making it a self contained system, additionally the formula editor provides a real-time syntax checking for expressions.
