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.
