• The IMSL Numerical Libraries have been the cornerstone of high-performance and desktop computing applications in science, technical and business environments for well over three decades. These embeddable mathematical and statistical algorithms are used in a broad range of applications -- including programs that help airplanes fly, predict the weather, enable innovative study of the human genome, predict stock market behavior and provide risk management and portfolio optimization. The algorithms embody the combination of High Performance Computing and High Productivity Computing.Significant benefits can be realized with the product’s ability to accelerate development time, reduce coding hassle, improve quality, and reduce development costs.
• Embeddable Mathematical and Statistical Functionality
• The IMSL Libraries are a comprehensive set of mathematical and statistical functions that programmers can embed into their software applications. The libraries save development time by providing pre-written mathematical and statistical algorithms that can be embedded into C, C# for .NET, Java™ and Fortranapplications, enhancing return on investment and programmer productivity. The IMSL Libraries can also be used from Python using PyIMSL Studio or the PyIMSL wrappers. Beyond choice of programming language, the IMSL Libraries are supported across a wide range of hardware and operating system environments including Windows, Linux, Apple and many UNIX platforms.

• Numerical Analysis Algorithm Development: More costly than you may think
• Direct Time and Cost to Develop In-House
• To just research and develop one numerical analysis algorithm, it could take an effort of about 8 weeks.
• ?
• Indirect Time and Cost to Develop In-House
• In addition to direct costs for development, there are additional hidden costs associated with building your own routines, including:
• ?
• Maintenance
• Porting
• Testing and Quality Assurance
• Documentation
• Indirect development efforts could require approximately 16 weeks of work.
• ?
• This represents a total of 24 weeks to develop, test, port, and document one numerical analysis algorithm. Compare this to no more than five days to call, embed, and test an IMSL algorithm.
• ?
• This comparison represents over 95% savings in time and cost!
• ?
• Consider the opportunity costs as your top developers spend their time reinventing the wheel instead of using their domain knowledge to further develop your core application.
• ?
• Finally, who will provide support as developers move on?
