Computer Algebra Systems, we will concentrate on a few of them. Reduce and Axiom are based on Lisp. On the other hand Mathematica, Maple and MuPAD are based on C. Besides symbolic manipulations, all systems can also do numerical manipulations. The systems are not only an interactive environment operating in response to on-l防锈 发表于 2025-3-23 14:15:52

Applications,roduced in Chapters 6 and 7. The problems presented here relate to number theory, nonlinear dynamics, special functions in mathematics and physics, etc. In general, applications are categorized under different classes. In each application, the mathematical background is first described, followed byMucosa 发表于 2025-3-24 08:58:08
Lisp and Computer Algebra, manipulate lists easily. Lisp was developed in the 1950s by John McCarthy . It is one of the most commonly used languages for writing a computer algebra system. Reduce, Macsyma, Derive and Axiom are based on Lisp. The basic data types in Lisp are atoms and dotted pairs. Lists are built from doteardrum 发表于 2025-3-24 11:02:04
PVM and Abstract Data Types,putational problems can be solved by using the aggregate power of many computers. Applications, which may be written in Fortran 77, C or C++, can be parallelized by using message-passing constructs common to most distributed-memory computers. By sending and receiving messages, multiple tasks of an aanthesis 发表于 2025-3-24 15:42:34
Error Handling Techniques,t subsystems that either execute successfully or fail. Thus, local error checking should be implemented throughout the system for a sound program. It is, therefore, important to identify the possible source of errors. They could be caused by the programmer himself. This case includes the detection oheirloom 发表于 2025-3-24 22:09:55
Gnuplot and PostScript,nts in both two- and three-dimensional space. The original software was developed by Thomas Williams and Colin Kelley. It is available over a number of platforms, such as Unix, Atari, VMS, MS-DOS and OS/2. It accommodates many of the needs of today’s scientists for graphic data representation.mastoid-bone 发表于 2025-3-25 02:59:18
