- COMPUTER ALGEBRA IN PROLOG
- --------------------------
-
- Copyright 1987 S.Vaghi

-
-
- COMPUTER ALGEBRA IN PROLOG consists of four files:
-
- (READ.ME) is the present file.
-
- ALGEBRA.TXT is a short paper on computer algebra in Prolog.
- The paper is self-contained and includes the
- listings of the sample programs discussed, with
- several examples of applications.
- You can print it out on your Epson-compatible
- printer (it is formatted by a word processor,
- so if you browse through it on the screen you
- will see some "funny" characters appear).
-
- DIFFSV.PRO is a program in Prolog for the symbolic
- differentiation of algebraic functions.
-
- SIMPSV.PRO is a program in Prolog for the symbolic
- simplification of algebraic functions.
-
- The two programs are described in the paper, which should be
- read before using them.
-
- The programs run under PD Prolog (ver.1.9), a public domain Prolog
- developed by Bob Morein of Automata Design Associates, 1570 Arran Way,
- Dresher, PA 19025, who may be contacted to obtain a copy of the program.
-
- To run the programs you must have the file PDPROLOG.EXE
- You then proceed as follows
- enter
- pdprolog
- and at the prolog prompt '?-' first enter
- consult(diffsv).
- and, at the following prompt,
- consult(simpsv).
-
- At this point you are ready to run the examples discussed in the
- paper (or any other case involving algebraic functions).
- To get out of the PDPROLOG environment and come back to DOS,
- enter
- exitsys.
- after the prompt.
-
-
- The programs should also run with little or no modification under
- other Prolog interpreters or compilers following the Edimburgh
- syntax.
-
-
- COMPUTER ALGEBRA IN PROLOG is placed in the public domain, but
- the author retains the copyright of the paper and programs.
-
- You may copy and distribute COMPUTER ALGEBRA IN PROLOG provided
- that it is done free of charge, that all four files are copied
- without modifications and, in particular, the copyright notices
- are not removed or changed.
-
- I hope you will enjoy these programs.
