THE MATHWORKS, INC. INTRODUCES THE SYMBOLIC MATH TOOLBOX

Comprehensive Environment for Integrated Numeric and Symbolic Computation
offers speed, accuracy, and reliability

Natick, Mass., September 6, 1993 - The MathWorks, Inc., developers of
MATLAB, today introduced the Symbolic Math Toolbox and the Extended
Symbolic Math Toolbox, two extensions to MATLAB that integrate powerful
symbolic computing with high performance numeric computation. Both
products, which begin shipping next month, are based on embedded versions
of Maple V, developed by Waterloo Maple Software. These are the first
products resulting from The MathWorks' strategic alliance with Waterloo
Maple Software.

"Until now, users who need both numeric and symbolic computation have had
to make tradeoffs between speed and symbolic functionality with their
current packages," said Cleve Moler, chief scientist at The MathWorks.
"With the Symbolic Math Toolboxes, scientists, engineers, and other
technical professionals can easily combine the speed, numeric robustness,
and vertical application tools of MATLAB with the symbolic computational
power and specialized mathematical tools of Maple V.

"In a typical engineering task such as dynamic system modeling, the
engineer initially uses calculus to develop a theoretical model, which
requires symbolic computing for an exact analytical solution. Numeric
computation is useful in the next stage, in testing the model on large
amounts of data or using it to perform simulations," added Moler. "We have
taken a major step forward by offering the best of both worlds in a single
package -- the industry-leading numeric computing software and the
industry's most highly regarded symbolic package -- without making
compromises on accuracy or performance."

The Symbolic Math Toolbox includes new MATLAB commands for more than 50 of
the most commonly used symbolic functions in Maple. The toolbox also
provides commands for variable precision arithmetic, direct access to the
Maple kernel and Maple's core math library and linear algebra module,
which come with the product. MATLAB users can access the full range of
Maple functions via a new "maple" command.

The Extended Toolbox is a superset that includes access to Maple's
programming language, the ability to create and execute Maple functions
and applications, and the complete set of more than 20 Maple software
packages for specialized fields such as number theory, power series, and
geometry.

MATLAB is the most powerful numeric computing environment available today,
providing hundreds of math and visualization functions such as matrix
computation, numerical analysis, signal processing, object-oriented
graphics, image display, animation, and more. MATLAB's 4GL programming
language, graphics, and application-specific toolboxes allow users to
analyze and visualize data, analyze and optimize engineering systems
designs and algorithms, and create mathematical models.

Pricing for the Symbolic Math Toolbox will be $495, and the Extended Math
Toolbox will be $695. University discount pricing for the Symbolic Math
Toolbox will be $195, and the Extended Math Toolbox will be $495. The
first platforms to become available will be the Sun SPARCstation and
Microsoft Windows 3.1. Versions for other MATLAB platforms, including
Macintosh, HP 700 series, Silicon Graphics, IBM RISCsystem/6000, Digital
DECstation Ultrix, Alpha OSF/1 and VAX/VMS will become available later
this year.

MATLAB Toolboxes extend the product by adding specialized functions for
particular applications. These include neural networks, signal processing,
control system design and analysis, system identification, and
optimization. The toolboxes are created by world class experts in their
respective fields and represent theory and algorithms at the cutting edge
of scientific and engineering research.

Maple is the most powerful interactive computer algebra system for symbolic
computation. Maple can solve the widest range of problems of any computer
algebra system on the market, and speeds through elaborate calculations
that would take hours or days to do on paper. It is widely recognized as
providing reliable, accurate results.

Waterloo Maple Software is a private company founded in 1988 to market,
distribute, and support MAPLE symbolic math software. The Maple software
program was created in 1980 when Professors Gaston Gonnet and Keith Geddes
of the University of Waterloo in Waterloo, Ontario, Canada joined together
to produce the first symbolic math software product for minicomputers.
Maple V is currently used by more than 100,000 engineers, scientists,
mathematicians and students worldwide, and installations include some of
the most prestigious universities in the world. Maple V is available for
many UNIX platforms, Microsoft Windows, DOS, Macintosh, NeXT, VAX/VMS, and
AmigaDOS systems.

The MathWorks, Inc., based in Natick, Mass., develops, markets and supports
high performance software for interactive numeric computation,
visualization and dynamic system simulation. The MathWorks' products are
used worldwide by more than 140,000 users at leading commercial and
government research laboratories and organizations, as well as at hundreds
of educational institutions. MATLAB is available for MS-DOS and Apple
Macintosh PCs; Sun, HP, Digital, IBM and Silicon Graphics workstations;
VAX/VMS computers; and Convex and Cray supercomputers.
