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](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](https://github.com/Reference-LAPACK/lapack).
|
|
LAPACK releases are also [available on netlib](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 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](https://cmake.org/) 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 `$HOME/.local/lapack/` is:
|
|
```sh
|
|
mkdir build
|
|
cd build
|
|
cmake -DCMAKE_INSTALL_LIBDIR=$HOME/.local/lapack ..
|
|
cmake --build . -j --target install
|
|
```
|
|
- LAPACK can be built and installed using [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
|
|
```sh
|
|
git clone https://github.com/Microsoft/vcpkg.git
|
|
cd vcpkg
|
|
./bootstrap-vcpkg.sh # ./bootstrap-vcpkg.bat for Windows
|
|
./vcpkg integrate install
|
|
./vcpkg install lapack
|
|
```
|
|
The lapack port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.
|
|
|
|
## 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
|
|
email to [the LAPACK team](mailto:lapack@icl.utk.edu).
|
|
|
|
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 the [GitHub issue tracker](https://github.com/Reference-LAPACK/lapack/issues).
|
|
|
|
For further information on LAPACK please read our [FAQ](http://www.netlib.org/lapack/faq.html)
|
|
and [Users' Guide](http://www.netlib.org/lapack/lug/lapack_lug.html).
|
|
A [user forum](http://icl.cs.utk.edu/lapack-forum/) and specific information for
|
|
[running LAPACK under Windows](http://icl.cs.utk.edu/lapack-for-windows/lapack/).
|
|
is also available to help you with the LAPACK library.
|
|
|
|
|
|
## 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](http://www.netlib.org/lapack/lapacke.html)
|
|
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.
