Math Libraries and Interactive Tools
Users often ask which mathematics libraries and interactive mathematical tools are "available" on which LC systems. The answer depends on what you regard as availability and on how much customization you need (or are willing to perform). Some mathematics libraries, mostly from commercial vendors, are preinstalled as compiled (object) code. The libraries sometimes overlap. Some routines are optimized and some are not; some are threaded and some are not; some support MPI and some do not; some are portable and some are not; some are single or double precision. Only your own computational needs can determine which of these competing libraries are most appropriate for your work.
Mathematics or numerical libraries are designed to be incorporated into user applications. They contain highquality implementations of common tasks such as linear algebra solvers or fast Fourier transforms.
In addition to the relatively small set of preinstalled math libraries, there is a much larger set of downloadable sourcecode math software routines and packages (around 1400 in all) on both OCF (CZ and RZ) and SCF, at the LINMath Web site. This semiinteractive site offers four different collections (SLATEC, PMATH, MSSL, and mssl3) of nonproprietary software, organized by problem type. The software addresses a wide range of mathematical and statistical problem types, from simple (e.g., vector operations) to complex (e.g., differential equation solvers), and represents the result of efforts in the numerical math research community since the 1970s. LINMath also provides links to many other popular math software packages that are available elsewhere. The LINMath routines and packages also overlap somewhat with the commercial libraries (BLAS is an example), so in those cases you must decide which alternative best meets your specific needs.
Interactive mathematical tools are standalone applications that can be used for numerical analysis, data analysis, and display. These tools have both a GUI and a commandline interface.
The table below shows at a glance which major libraries and interactive mathematical tools reside on which LC machines. Each library or tool name is a link to more information about that library or tool.
