Symbmath takes complex problems out of maths, Uniken, 1994, July 29, 1. ------------------- The magazine <>, June 1992, page 119, reviewed, "SymbMath 1.4 belongs in a more esoteric field, that of symbolic mathematics. If you've ever had need for programs such as Maple or Mathematica, you'll know about symbolic mathematics, also called algebraic computation or symbolic manipulation. SymbMath is a symbolic calculator that can manipulate complicated formulas and return answers in terms of symbols. It solves the same sort of problems as programs like Mathematica, but still runs in 640 K of RAM as opposed to Mathematica's 4 Mb plus. Although SymbMath is still being added to, it has generated interest in the scientific sections of some overseas electronic bulletin boards, being one of the most frequently downloaded programs at some monitored sites". ___________________________________________________________________________ The <> journal on February 1992, page 76, said "SymbMath, an expert system that solves mathematic problems in symbolic formula or through numeric computation ... requires significantly less RAM than most comparable software - 640 Kbytes, as opposed to as much as 4 Mbytes". ____________________________________________________________________________ The <> magazine on 1993 July, page 147, reviewed "SymbMath 2.0 is a symbolic calculator that can manipulate complicated formulas and return answers in term of symbols. It solves the same sort of problems as programs such as Mathematica and Maple (and some that they can't), yet runs within 640K of RAM." ___________________________________________________________________________ <>, the June 1993 issue, page 281, reviewed SymbMath as follows. SUPPLIER: Public Domain and Shareware Library PHONE: (0892) 663298 FOR: Powerful maths functions Automatically learns from user input Modest hardware requirements AGAINST: Needs advanced maths knowledge PCPLUS VALUE VERDICT: xxx REQUIREMENTS: MINIMUM HARDWARE: DRIVES: Hard disk, RAM: 640 Kb * Mathematics whizzes should find a capable facility for handling complex problems. Symbmath, short for Symbolic Mathematics, is both an advanced mathematical calculator and an expert system. Designed by Australian Weiguang Huang for solving university and professional level symbolical maths problems. will also perform exact numerical computation. It's able to manipulate extremely complicated formulae, returning answers in terms of symbols, formulae, or exact numbers as required. The program can learn from your calculations, automatically adding your problem-solving techniques to its repertoire: making it of interest to artificial intelligence researchers as well as mathematicians, particularly as you don't have to write any code. Its capabilities are impressive, going well beyond the facilities offered by rival programs. It's very fast and includes wide-ranging and sophisticated routines for differentiation, integration, equation solving, algebraic calculations, exact and floating point numerical computation of numbers ranging from plus to minus infinity, and an ex- tensive array of other advanced facilities that will be more than enough to handle academic or practical mathematical problems of even extreme complexity. Despite this extensive computing power, will nevertheless run on very basic hardware: you need at least 640 Kb of RAM and a hard disk, but an 8088-based PC with a monochrome monitor is ample for even very convoluted calculations. You'll need to be well-schooled in advanced maths but, if you are, you'll will find , well worth investigating. ____________________________________________________________________________ <>, Vol. 18, No. 2, May 1993, page 58, reviewed SymbMath: "An alternative for MS-DOS users which has the unique advantage of being `home grown', SymbMath is the only Australian-made computer algebra system of which I am aware. SymbMath comes in three versions (shareware, student and advanced), with corresponding increases in price and in capabilities. The student version is reviewed here, and was found to be a versatile and useful mathematical tool. Like Maple on Macintosh, mathematical input must be entered in `computer syntax', but SymbMath (like Maple V and Derive) has the option of two-dimensional output, which provides a reasonable approximation of mathematical notation. Its capabilities are impressive, including a `chemistry' option, in which it performs chemical calculations and operates on chemical equations, and a unique ability to `learn' from the user. Entering a rule for differentiation, for example, automatically `teaches' the program how to integrate using that rule; trigonometric identities and algebraic formulas can likewise be used as the basis for inference. At the same time, the programs provide more than adequate computer algebra capabilities, and represent excellent value for money." ____________________________________________________________________________ <> magazine, December 1993, page 665, reviewed: "SymbMath 2.2 (an abbreviation for Symbolic Mathematics) is a software package for symbolic computation. It runs on IBM PC compatible under DOS and requires only 420 KBytes of memory. It is an integrated software package with pull-down and pop-up menus, on-line help and on- line manuals which make application easier. The diskette also contain a detailed manual with many examples. SymbMath performs both exact numerical computations and evaluates symbolic formulae. The package has the capability of solving mathematical expressions, simultaneous equations, limits, differentiation, integration, sums and products etc. It is also a programming language working as an interpreter with variety of types, loops, arrays, functions etc. which enable writing of programs for solving of more complex mathematical procedures. This also enables documentation of your calculations. The package is very easy to apply. The user just needs to type the command for the required mathematical operation, and the expression(s). Mathematical problems which usually require lots of calculation time can be solved quickly. SymbMath has the ability to deduce and expand its knowledge. Provided with neccessary facts, the package may solve many problems that they were unable to solve before e.g. integrals etc. There is a chemical calculation package which is capable of stoichiometric calculations as well as an inorganic reaction package which may provide answers for some inorganic chemical reactions. It also performs plots of functions and data and interface with other software. Like the other software packages for symbolic mathematics e.g. Mathematica, MAPLE etc., SymbMath is suitable for performing calculations of expressions, solving various mathematical problems, or performing preliminary analysis before solving very complex mathematical problems. The availability of such software has already had an impact on teaching mathematics at universities and there will be more applications for such packages in the future because they enable easy solution of diverse mathematical problems. Compared with large packages like Mathematica capable of solving very complex problems (which runs under Microsoft Windows which itseft require a very large memory), SymbMath has a big advantage in that it requres very little memory, it is much easier to learn and it is much less expensive. I would highly recommand the package for anyone who uses mathematics in their work." __________________________________________________________________________ <> on August 1993, Vol. 8, No. 4, page 99, reviewed: "SymbMath 2.2 is an expert system for solving symbolical math problems and performing exact numeric computations. It can manipulate complicated formulas and return answers in terms of symbols, formulas, and exact numbers. It also learns from users; for instance, it can learn the integrals of an unknown function from a derivatives of the function. The shareware version is available from Simtel20 archives on anonymous FTP sites (rana.cc.deakin.oz.au as /huang/sm22a.zip) or by e-mail from listserv@vm1.nodak.edu or listserv@ndsum1.bitnet. Student and Advanced versions are also available." ------------------------------------------------------------------------- The <> magazine on 1994 July, page 257, reviewed "SymbMath - a symbolic calculator that can manipulate complicated formulas and return answers in term of symbols in the same category as more expensive programs such as Mathematica." -------------------------------------------------------------------------- Newspapers <> on July 7, 1994, page 12, published a review titled "Symbmaths is for serious numbers". -------------------------------------------------------------------------- Newspapers <> on July 29, 1994, page 1, published half-page of an article titled "SymbMath program takes complex problems out of maths". --------------------------------------------------------------------------- Magazine <> on September 1994, page 39-40, said: "Dr Weiguang Huang, who is obviously something of a beaver brain, has developed a piece of software called SymbmMath 3.1. Based on symbolic maths principles, the program will perform exact numeric, symbolic and algebraic calculations. It is also clever enough to learn from the user's input, such as integrals of an unknown function."
