LAPACK is a library of Fortran subroutines for solving the most commonly occurring problems in numerical linear algebra. LAPACK is a freely-available software package. It can be included in commercial software packages (and has been). We only ask that that proper credit be given to the authors, for example by citing the LAPACK Users' Guide. The license used for the software is the modified BSD license. LAPACK is available from GitHub. LAPACK releases are also available on netlib. Installation LAPACK can be installed with make . The configuration must be set in the make.inc file. A make.inc.example for a Linux machine running GNU compilers is given in the main directory. Some specific make.inc are also available in the INSTALL directory. LAPACK includes also the CMake build. You will need to have CMake installed on your machine. CMake will allow an easy installation on a Windows Machine. An example CMake build to install the LAPACK library under $HOME/.local/lapack/ is: LAPACK can be built and installed using vcpkg dependency manager: LAPACK has been thoroughly tested, on many different types of computers. The LAPACK project supports the package in the sense that reports of errors or poor performance will gain immediate attention from the developers. Such reports, descriptions of interesting applications, and other comments should be sent by email to the LAPACK team. A list of known problems, bugs, and compiler errors for LAPACK is maintained on netlib. Please see as well the GitHub issue tracker. For further information on LAPACK please read our FAQ and Users' Guide. A user forum and specific information for running LAPACK under Windows are also available to help you with the LAPACK library. LAPACK includes a thorough test suite. We recommend that, after compilation, you run the test suite. For complete information on the LAPACK Testing please consult LAPACK Working Note 41 "Installation Guide for LAPACK". LAPACK now includes the LAPACKE package. LAPACKE is a Standard C language API for LAPACK that was born from a collaboration of the LAPACK and INTEL Math Kernel Library teams.

LAPACK (Linear Algebra PACKage) 数値線形代数のための数値解析ソフトウェアライブラリで、線型方程式や線型最小二乗問題、固有値問題、特異値問題等を数値的に解くために利用される。本ライブラリは複素数または実数を成分とする行列を扱うことが可能であり、LU分解やコレスキー分解、QR分解、シュア分解等の行列の分解を行うためのサブルーチンを含む。サブルーチンは単精度版と倍精度版が提供される。1992年のLAPACKの初版はFORTRAN 77 で実装されていたが、現在はFortran 90が用いられている。LAPACK 3.4.0からはC言語インターフェースであるLAPACKEが統合され、C言語やC++からの利用が容易になった。 LAPACKはLINPACKおよびEISPACKの後継と見做されている。ただし、LINPACKの設計が開発当時近代的であった共有メモリ型ベクトルコンピュータを意識したものであるのに対して、本ライブラリの設計はキャッシュを用いたアーキテクチャを有する、より近代的なコンピュータを意識したものである。LAPACKはLINPACK同様にBLAS(Basic Linear Algebra Subprograms、基本線型代数サブプログラム群)ライブラリ上に構築されている。LAPACKは後に分散メモリ型のコンピュータ向けにやへと拡張された。 LAPACKはBSDライセンスで提供されるオープンソースソフトウェアである。
