Wolfram Research Adds the MathLink Communication Standard to Its New
Windows Version of Mathematica - Users Can Now Exchange Information with
Other Desktop Applications

June 2, 1994 -- CHAMPAIGN, Illinois--Wolfram Research, Inc., has added a
new communication protocol called MathLink to Mathematica 2.2.2 for
Windows, the leading software for technical computation. MathLink lets
users make seamless connections between Mathematica, their own code, and
other commercially available software applications. MathLink saves both
time and money because it allows users to exchange information between
Mathematica and programs they have already written or software they have
already purchased. With MathLink, users can take advantage of two programs
working together to achieve reliable results.

"MathLink gives technical professionals a double advantage," explains Shawn
Sheridan, manager, MathLink development, Wolfram Research. "Now, users can
call on the power of Mathematica from within their favorite applications,
or add to Mathematica's functionality by calling on their own external
programs."

Calling External Programs from Mathematica

It is a simple matter to add a MathLink interface to an existing program.
With MathLink users can call their own specialized algorithms, functions,
and optimized C or FORTRAN programs from Mathematica. A user working in
Mathematica, for example, can call upon an existing external package to
manipulate a large set of data from a database.

Calling Mathematica from Another Program

A simple MathLink program is all that is needed to call Mathematica from an
existing customized program. By using MathLink in this way, users can work
freely within their own program and call upon the computational power of
Mathematica whenever needed. MathLink for Excel, developed by Wolfram
Research, for example, lets a Microsoft Excel user ask Mathematica to
solve a differential equation from within Excel. This is a simple task for
Mathematica, and with MathLink, it becomes simple for Excel.

Using MathLink to Connect Several Mathematica Kernels

Mathematica is divided into two parts: the kernel, which actually performs
computations, and the front end, which handles the interaction with users.
Users with problems that require more computing power than a single
machine can supply, can access several machines at once by connecting
multiple Mathematica kernels with MathLink.

MathLink-Compatible Applications

MathLink is designed so that users can easily create connections to the
programs of their choice. Wolfram Research has created worked with a
number of developers to create MathLink connections to a broad range of
commercially available applications. Some of the most commonly used
MathLink-compatible applications are Microsoft Excel, LabView, Visual
Basic, Spyglass Transform, and AVS. Additional examples of MathLink
connections are available free of charge from MathSource, Wolfram
Research's electronic resource for Mathematica-related materials. To
review available MathLink connections on MathSource, send the email
message Help Intro to mathsource@wri.com.

MathLink Availability

MathLink is a standard part of the enhanced version of Mathematica 2.2.2,
which takes advantage of a numeric coprocessor. Mathematica ships with a
MathLink Developer Kit which includes MathLink libraries, interface files,
example programs, and other tools needed to make MathLink connections.
Additionally, the Developer Kit includes the MathLink Reference Guide,
which gives a practical introduction to MathLink as well as instructions
for creating MathLink-compatible applications. MathLink is available on
Macintosh, Microsoft Windows, and Unix platforms.

About Mathematica and Wolfram Research, Inc.

Mathematica, the leading software for numeric, symbolic, and graphical
computation, is used internationally by technical professionals in almost
every area of scientific and technical computing. Its underlying,
high-level programming language is becoming the language of choice for
programming among technical professionals and students. Mathematica is
available on more than 20 systems, including Microsoft Windows, Unix,
Macintosh, MS-DOS, and NEXTSTEP.

Wolfram Research distributes Mathematica worldwide directly as well as
through a variety of channels, including resellers, distributors, retail
outlets and hardware vendors. Wolfram Research Europe Ltd., based in the
United Kingdom, handles distribution in Europe. For further information on
