About

Questions with the tag should not be just about a specific library; those questions should be tagged with a tag specific to that library (see examples below). Rather, these questions should be more general: about the creation, testing, and usage of libraries in the abstract. Also appropriate are inquiries about what libraries have a given functionality or comparisons between multiple libraries (though in the latter case, it should also be tagged with the relevant libraries, if possible).

Examples of libraries:

  • BLAS http://netlib.org/blas/ Routines that provide standard building blocks for performing basic vector and matrix operations. One implementation of this is ATLAS
  • LAPACK http://www.netlib.org/lapack/ A Fortran 90 library that provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.
  • PETSc http://www.mcs.anl.gov/petsc/ A suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations.
