|
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, see:
|
|
https://github.com/Reference-LAPACK/lapack/blob/master/LICENSE
|
|
|
|
Like all software, it is copyrighted. It is not trademarked, but we do ask the
|
|
following: if you modify the source for these routines we ask that you change
|
|
the name of the routine and comment the changes made to the original.
|
|
|
|
We will gladly answer any questions regarding the software. If a modification
|
|
is done, however, it is the responsibility of the person who modified the
|
|
routine to provide support.
|
|
|
|
LAPACK is available from github at:
|
|
https://github.com/reference-lapack/lapack
|
|
|
|
LAPACK releases are also available on netlib at:
|
|
http://www.netlib.org/lapack/
|
|
|
|
The distribution contains (1) the Fortran source for LAPACK, and (2) its
|
|
testing programs. It also contains (3) the Fortran reference implementation of
|
|
the Basic Linear Algebra Subprograms (the Level 1, 2, and 3 BLAS) needed by
|
|
LAPACK. However this code is intended for use only if there is no other
|
|
implementation of the BLAS already available on your machine; the efficiency of
|
|
LAPACK depends very much on the efficiency of the BLAS. It also contains (4)
|
|
CBLAS, a C interface to the BLAS, and (5) LAPACKE, a C interface to LAPACK.
|
|
|
|
## Installation
|
|
|
|
- LAPACK can be installed with `make`. The configuration have to 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 is available at http://www.cmake.org/). CMake will
|
|
allow an easy installation on a Windows Machine.
|
|
An example CMake build is:
|
|
```sh
|
|
mkdir build
|
|
cd build
|
|
cmake -DCMAKE_INSTALL_LIBDIR=$HOME/.local/lapack ..
|
|
cmake --build -j . --target install
|
|
```
|
|
That installs the LAPACK library under $HOME/.local/lapack/
|
|
- Specific information to run LAPACK under Windows is available at
|
|
http://icl.cs.utk.edu/lapack-for-windows/lapack/.
|
|
|
|
|
|
## User Support
|
|
|
|
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
|
|
electronic mail to lapack@icl.utk.edu.
|
|
|
|
For further information on LAPACK please read our FAQ at
|
|
http://www.netlib.org/lapack/#_faq.
|
|
|
|
A list of known problems, bugs, and compiler errors for LAPACK is
|
|
maintained on netlib
|
|
http://www.netlib.org/lapack/release_notes.html.
|
|
Please see as well
|
|
https://github.com/Reference-LAPACK/lapack/issues.
|
|
|
|
A User forum is also available to help you with the LAPACK library at
|
|
http://icl.cs.utk.edu/lapack-forum/.
|
|
You can also contact directly the LAPACK team at lapack@icl.utk.edu.
|
|
|
|
|
|
## Testing
|
|
|
|
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".

|
## LAPACKE
|
|
|
|
LAPACK now includes the LAPACKE package. LAPACKE is a Standard C language API
|
|
for LAPACK This was born from a collaboration of the LAPACK and INTEL Math
|
|
Kernel Library teams. See:
|
|
http://www.netlib.org/lapack/#_standard_c_language_apis_for_lapack.
