VISUAL NUMERICS ANNOUNCES JMSL 2.0 FOR
JAVA TECHNOLOGY DEVELOPERS

Real-time Data Analysis and Visualization for Collaboration and Sharing

SAN RAMON, Calif. - July 23, 2002 - Visual Numerics, Inc., a leading provider of visualization and numerical analysis software, today announced JMSL 2.0, a new level of comprehensive mathematical, statistical and charting classes written for the Java™ platform. JMSL is the only solution that combines the reliable mathematical and statistical functionality of the industry-leading IMSL™ set of algorithms with the network-centric, platform independent Java platform. The result is a product that will allow developers to create network applications that perform complex data analysis and visualization across multiple groups or regions to enable sharing and collaborative decision-making in real-time. These extensive libraries are used by scientists, researchers, engineers, financial analysts of major corporations, academic institutions and research laboratories worldwide for immediate analysis and visualization of complex data.

"Many industries such as manufacturing companies and financial institutions pull data from thousands of sources and need that data to be analyzed accurately and reliably in real-time," said Phil Fraher, EVP of Visual Numerics. "For example, a bank may need to pull financial data from across multiple sources and stock markets for strategic customer financial management and portfolio optimization. When dealing with people's finances, banks cannot have the slightest margin of error in that data analysis. With JMSL 2.0, companies can now get reliable data analysis in real-time because our product is based on 30 years of tested and trusted algorithms. And, our 2D charting capabilities let companies visualize that data and, because it's Java-based, they can share results across regions for collaborative decision-making." "Priceline.com chose JMSL because of its ease of use and its flexibility" said Sanjay Tiwary, Vice President of CIS, Priceline.com

JMSL is the first visualization and numerical analysis tool with charting capabilities available for the Java platform. The Java platform is ideal for a networked environment since the technology is based upon open standards and works with any application or platform. The Java technology's Write Once, Run Anywhere™ capability makes it ideal for complex network-centric applications, like those built with JMSL. The portability of Java technology means that developers can write one application and run it across multiple platforms, even when that application handles complex data analysis pulling from multiple systems, databases, and content sources often written in legacy languages.

Visual Numerics has been leading the way with analysis tools written in Java since 1997. Its Java math and stat library is based on the company's industry standard IMSL Libraries, which have been trusted by C/C++ and FORTRAN developers for over 30 years. Since IMSL's introduction over three decades ago, it has become the world's most widely used, robust, and fully supported set of mathematical and statistical algorithms for developing data analysis and visualization applications. There are thousands of users in the aerospace, finance, manufacturing, medical, and semiconductor industries as well as educational institutions, environmental organizations, and governmental agencies that have relied on the IMSL Libraries in C/C++, FORTRAN and Java to write their business critical analysis and visualization applications. JMSL is the first and only comprehensive and time-tested set of Java Numerics available today that is based on the leading IMSL Libraries with the added benefit of 2-D charting, and is optimized for collaboration and sharing across the enterprise.

• Pure Java analysis and flexible, easy to use charting - all in one product
• A significant addition of more mathematical and statistical algorithms built on the robust and trusted IMSL Libraries for a wider breadth of analysis options
• Date and time support for time-sensitive analysis
• Extended documentation in both Javadoc and hardcopy manuals

"Whether developing standalone or web-enabled applications, analysts need a robust, reliable and accurate set of algorithms to analyze and visualize data quickly, and share it across the organization," said Peter Denyer, Group Manager, Design and Analysis, Sun Microsystems, Inc. "JMSL provides a comprehensive library of Java Numerics, plus 2D charting for network-centric, high performance data analysis. JMSL 2.0 is a great example of why the Java platform is the standard for applications that require portability, interoperability as well as availability and reliability."

Pricing is dependent upon development and deployment requirements. A single Development License costs US$4,995 plus support.
