32 LAPACK is a library of Fortran subroutines for solving the most commonly
33 occurring problems in numerical linear algebra.
35 LAPACK is a freely-available software package. It can be included in commercial
36 software packages (and has been). We only ask that that proper credit be given
37 to the authors, for example by citing the LAPACK Users' Guide. The license used
38 for the software is the modified BSD license, see:
39 https://github.com/Reference-LAPACK/lapack/blob/master/LICENSE
41 Like all software, it is copyrighted. It is not trademarked, but we do ask the
42 following: if you modify the source for these routines we ask that you change
43 the name of the routine and comment the changes made to the original.
45 We will gladly answer any questions regarding the software. If a modification
46 is done, however, it is the responsibility of the person who modified the
47 routine to provide support.
49 LAPACK is available from github at:
50 https://github.com/reference-lapack/lapack
52 LAPACK releases are also available on netlib at:
53 http://www.netlib.org/lapack/
55 The distribution contains (1) the Fortran source for LAPACK, and (2) its
56 testing programs. It also contains (3) the Fortran reference implementation of
57 the Basic Linear Algebra Subprograms (the Level 1, 2, and 3 BLAS) needed by
58 LAPACK. However this code is intended for use only if there is no other
59 implementation of the BLAS already available on your machine; the efficiency of
60 LAPACK depends very much on the efficiency of the BLAS. It also contains (4)
61 CBLAS, a C interface to the BLAS, and (5) LAPACKE, a C interface to LAPACK.
65 - LAPACK can be installed with `make`. The configuration have to be set in the
66 `make.inc` file. A `make.inc.example` for a Linux machine running GNU compilers
67 is given in the main directory. Some specific `make.inc` are also available in
68 the `INSTALL` directory.
69 - LAPACK includes also the CMake build. You will need to have CMake installed
70 on your machine (CMake is available at http://www.cmake.org/). CMake will
71 allow an easy installation on a Windows Machine.
72 - Specific information to run LAPACK under Windows is available at
73 http://icl.cs.utk.edu/lapack-for-windows/lapack/.
78 LAPACK has been thoroughly tested, on many different types of computers. The
79 LAPACK project supports the package in the sense that reports of errors or poor
80 performance will gain immediate attention from the developers. Such reports,
81 descriptions of interesting applications, and other comments should be sent by
82 electronic mail to lapack@icl.utk.edu.
84 For further information on LAPACK please read our FAQ at
85 http://www.netlib.org/lapack/#_faq.
87 A list of known problems, bugs, and compiler errors for LAPACK is

93 A User forum is also available to help you with the LAPACK library at
94 http://icl.cs.utk.edu/lapack-forum/.
95 You can also contact directly the LAPACK team at lapack@icl.utk.edu.
100 LAPACK includes a thorough test suite. We recommend that, after compilation,
101 you run the test suite.
103 For complete information on the LAPACK Testing please consult LAPACK Working
104 Note 41 "Installation Guide for LAPACK".

113 LAPACK now includes the LAPACKE package. LAPACKE is a Standard C language API
114 for LAPACK This was born from a collaboration of the LAPACK and INTEL Math
115 Kernel Library teams. See:
