The ScaLAPACK (or Scalable LAPACK) library includes a subset of LAPACK routines redesigned for distributed memory MIMD parallel computers. It is currently written in a Single-Program-Multiple-Data style using explicit message passing for interprocessor communication. It assumes matrices are laid out in a two-dimensional block cyclic decomposition.

SLATEC is a comprehensive software library containing over 1400 general purpose mathematical and statistical routines written in Fortran 77.

This is an ANSI C++ implementation of the complete ANSI C specification of Chapter 3 of the BLAS Technical Forum Standard. The distribution is quite small and it is meant as a starting point for developing an optimized and architecture-dependent version. (C++ was used, rather than C, as it has support for complex arithmetic and templates to facilitate to creation of various precision codes.) The library includes support for all four precision types (single, double precision, real, and complex) and Level 1, 2, and 3 operations.

The TiMBL software package is a fast, decision-tree-based implementation of k-nearest neighbor classification. The package includes the IB1, IB2, TRIBL, TRIBL2, and IGTree algorithms, and offers various weighting metrics.

Wcalc is a powerful arbitrary-precision calculator. It has standard functions (sin, asinh, logtwo, floor, etc), many pre-defined constants (pi, e, c, etc.), variables, "active" variables, command history, and hex/octal/binary i/o, conversions, and more.

wxMaxima is a wxWidgets GUI for the computer algebra system maxima. Most of maxima functions are accessible through menus, some have dialogs. The input line has command history (up-key, down-key) and completion based on previous input (tab-key). wxMaxima provides 2d formated display of maxima output.

This library of routines is part of a reference implementation for the Dense and Banded BLAS routines, along with their Extended and Mixed Precision versions, as documented in Chapters 2 and 4 of the new BLAS Standard. EXTENDED PRECISION is only used internally; the input and output arguments remain the same as in the existing BLAS. At present, we only allow Single, Double, or Extra internal precision. Extra precision is implemented as double-double precision (128-bit total, 106-bit significand). The routines for the double-double precision basic arithmetic operations +, -, *, / were developed by David Bailey. We have designed all our routines assuming that single precision arithmetic is actually done in IEEE single precision (32 bits) and that double precision arithmetic is actually done in IEEE double precision (64 bits). The routines also pass our tests on an Intel machine with 80-bit floating point registers. MIXED PRECISION permits some input/output arguments to be of different types (mixing real and complex) or precisions (mixing single and double).
