Source code

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) è un insieme di librerie software usate per effettuare calcoli scientifici ad alto livello. Tali librerie sono state scritte in Fortran 77 e sono distribuite sotto licenza BSD modificata. L'ultima versione è la 3.6.0 del 13 novembre 2015. Mediante queste librerie, è possibile effettuare calcoli di notevole importanza, come il calcolo di autovalori ed autovettori di matrici, risoluzione di sistemi lineari, fattorizzazioni di matrici, e molto altro ancora. Ad esempio, esistono delle procedure interne, nascoste all'utente, in grado di trasformare la matrice iniziale in una matrice tridiagonale, per poi calcolare effettivamente autovalori ed autovettori. Come dipendenza questa libreria richiede l'installazione di un'altra libreria: la (Basic Linear Algebra Subprograms). Le procedure all'interno di tale libreria consentono di effettuare calcoli scientifici di più basso livello, come al calcolo del prodotto scalare tra due vettori, prodotto matrice per vettore, etc.
