1572.0. "SymbMath new symbolic math/AI program" by STAR::ABBASI () Mon Feb 24 1992 01:32

    Hi, 
    There is a new and sounds interesting symbolic math program  called
     Symbmath, it is free through ftp access, i have not used ftp befor ,
    also i dont think our cluster has ftp support.
    if some one with ftp access wants to get a copy of this, could they 
    please send me a copy too?
    The information about it is below.
    Thank you,
    /nasser

        SymbMath 1.4: A Symbolic Calculator with Learning

	SymbMath, (an abbreviation for Symbolic Mathematics), is not
only a symbolic calculator but also an expert system that can solve 
symbolically mathematical problems. SymbMath performs symbolic formula, 
as well as exact numeric computation. It can manipulate complicated 
formulas and return answers in terms of symbols, formulas and exact 
numbers, not just floating-point numbers. Symbolic mathematics is also 
called Computer Algebra, Symbolic Manipulation, Algebraic Manipulation, 
Symbolic Computation, or Algebraic Computation. 
        SymbMath is different from other software. (1) It
only require 640 KBytes RAM, so it can run on small IBM PC under 
MS-DOS. (2) It is able to learn from human as machine learning. If 
users only show it one thing (e.g. one integral) without writing any 
line of program, it will learn many relative knowledges (e.g. many 
integrals) although it has no these predefined knowledges before. (3) 
Users easily edit the library (e.g. integral tables) in the formula 
format. (4) It can do something that other software cannot do.
	Its capabilities include facilities to provide analytical and 
numerical answers for:
	1. Differentiation: derivatives, higher order derivatives, 
partial derivatives, mixed derivatives, total derivatives, implicit
differentiation.
	2. Integration: indefinite integration, definite integration, 
multiple integration, infinite integration, parametric integration, 
iterated integration, line integration, surface integration, 
discontinuous integration, implicit integration.
	3. Solution of equations: polynomial equations, algebraic 
equations, systems of equations, differential and integral equations.
	4. Manipulation of expressions: simplification, factorisation, 
expansion, substitution, evaluation, user-defined functions, built-in 
standard functions (including the error function).
	5. Calculation: exact and floating-point numerical computation 
of integer, rational, real and complex numbers in the range from 
-infinity to infinity, even with different units.
	6. Limits: real limits, complex limits, one-sided limits, 
including the indeterminate forms, (e.g. 0/0, infinity/infinity, etc.).
	7. Chemical calculation: the molecular weights, atomic weights, 
and concentrations, by entering the symbols of the chemical elements.
	8. Chemical reactions: inorganic and organic chemical reactions.
	9. Others such as extrema, Taylor series, lists, arrays, vectors,
matrices, sum, product, etc.
	Its features also include:
	1. Programming as an interpreter.
	2. Interface with other software (e.g. with PlotData for graph).
        3. Outputting two-dimentional displays, and the BASIC format.
	4. On-line help, on-line manual.
	5. Syntax check and the line editor for input.
	Shareware version of SymbMath, SM14A.ZIP, is available from 
the Calculator directory in SIMTEL20 on many anonymous FTP sites (e.g.
wsmr-simtel20.army.mil, garbo.uwasa.fi, rana.cc.deakin.oz.au, etc.).

	PlotData 1.1: A Plotter with Analysing Data

	Plotdata is a software package of a plotter with analysing
data. With PlotData, data can be plotted on the screen, viewed, 
edited, analysed, differentiated, integrated, calculated, and 
reproducted graphically. Many sets of data can be overlapped to solve 
systems of equations graphically. Users can zoom in and out graph.
	It offers an interactive menu environment for the easy to use, 
and on-line help.
	It can be interfaced with other software, e.g. SymbMath (a 
software package of a symbolic calculator), CurFit (a software package
of a separator of overlapping peaks) [1-3]. PlotData can read data in 
these software formats without any modification, in the BAS-100 
instrument format, and in many other data formats.
	If SymbMath is interfaced with PlotData, SymbMath 
produces the data table of the functions, and PlotData plots curves 
from the data table, as SymbMath seems to do graphics. Users can use 
this interface to make the pictures, to plot the function values, 
and to solve equations graphically.
	Its on-line help file is a text file, so users can edit it 
as they like.
	It runs on an IBM-PC with 200 KByte RAM under MS-DOS, the 
graphical monitors (CGA, EGA, or Hercules), or the dot matrix 
printers for the hardcopy.
	Shareware version of PlotData (PlotD11A.ZIP) is available
free from the Plot directory in SIMTEL20 on many anonymous FTP sites 
(e.g. wmrs-simtel20.army.mil, garbo.uwasa.fi, rana.cc.deakin.oz.au).
    

    Anytime you see the magic name SIMTEL20 you can likely substitute
    node winnah::"/ftp" and, using UNIX (tm) syntax, obtain the apropriate
    files.

    $ SPOOL COPY winnah::"/ftp/msdos/calculator/sm14a.zip" SM14A.ZIP
    
    will do what you want.  Since the .ZIP file is only 384 blocks, don't
    start thinking you have a MAPLE clone here.  But it might be fun.
    
    Have fun,

    Thanks John!  I got the .ZIP file, but what kind of file is this?
    is this some kind of weired unix file type ? i assume it is some
    kind of compressed source code? 
    now what do i do?
    Thanks!

    We are straying away from the conference area.  .ZIP is one PC
    equivalent of a BACKUP saveset.  To unpack the file you need PKUNZIP,
    shareware available from winnah::"/ftp/msdos/starter/pkz110eu.exe".
    Run it and it automagically creates a bunch of other .EXEs and docs,
    as well as the address to send your $25 or so registration fee.
    
    You DID realize this was all for PCs, didn't you?
    
      John

    Thank John, Yes, I knew it was for PC DOS, i knew that much at least.
