26 LAPACK is a library of Fortran 90 with subroutines for solving
27 the most commonly occurring problems in numerical linear algebra.
28 It is freely-available software, and is copyrighted.
30 LAPACK is available on netlib and can be obtained via the World Wide
31 Web and anonymous ftp.
33 http://www.netlib.org/lapack/
35 The distribution tar file contains the Fortran source for LAPACK and the
36 testing programs. It also contains the Fortran77
37 reference implementation of the Basic Linear Algebra Subprograms
38 (the Level 1, 2, and 3 BLAS) needed by LAPACK. However this code is
39 intended for use only if there is no other implementation of the BLAS
40 already available on your machine; the efficiency of LAPACK depends
41 very much on the efficiency of the BLAS.
45 - LAPACK can be installed with make. Configuration have to be set in the
46 make.inc file. A make.inc.example for a Linux machine running GNU compilers
47 is given in the main directory. Some specific make.inc are also available in
49 - LAPACK includes also the CMAKE build. You will need to have CMAKE installed
50 on your machine (CMAKE is available at http://www.cmake.org/). CMAKE will allow
51 an easy installation on a Windows Machine
52 - Specific information to run LAPACK under Windows are available at
53 http://icl.cs.utk.edu/lapack-for-windows/lapack/
55 For further information on LAPACK please read our FAQ at
56 http://www.netlib.org/lapack/#_faq
57 A User forum is also available to help you with the LAPACK library at
58 http://icl.cs.utk.edu/lapack-forum/
65 LAPACK has been thoroughly tested, on many different
66 types of computers. The LAPACK project supports the package in the
67 sense that reports of errors or poor performance will gain immediate
68 attention from the developers. Such reports, descriptions
69 of interesting applications, and other comments should be sent by
70 electronic mail to lapack@cs.utk.edu.
72 A list of known problems, bugs, and compiler errors for LAPACK is
74 http://www.netlib.org/lapack/release_notes.html
76 A User forum is also available to help you with the LAPACK library at
77 http://icl.cs.utk.edu/lapack-forum/
78 You can also contact directly the LAPACK team at lapack@cs.utk.edu
84 The complete package, including test code in four
85 different Fortran data types (real, complex, double precision, double
86 complex), contains some 805,000 lines of Fortran source and comments.
87 You will need approximately 33 Mbytes to read the complete tape.
88 We recommend that you run the testing. The total
89 space requirements for the testing for all four data
90 types, including the object files, is approximately 80 Mbytes.
92 A README file containing the information in this letter is located
93 in the LAPACK directory. Postscript and LaTeX versions of the Quick
94 Installation Guide are in the LAPACK/INSTALL directory, in the files
95 lawn81.tex, psfig.tex, lawn81.ps, and org2.ps. Consult the Installation
96 Guide for further details on installing the package and on what is contained
97 in each subdirectory. For complete information on the LAPACK Testing
98 please consult LAPACK Working Note 41 "Installation
105 It is highly recommended that you obtain a copy of the Third Edition of
106 the LAPACK Users' Guide published by SIAM in Winter, 1999. This Users'
107 Guide gives a detailed description of the philosophy behind LAPACK as well
108 as an explanation of its usage. The LAPACK Users' Guide can be purchased from:
109 SIAM; Customer Service; P. O. Box 7260; Philadelphia, PA 19104;
110 215-382-9800, FAX 215-386-7999. It will also be available from booksellers.
112 To order by email, send email to service@siam.org. The book is also
113 available via SIAM's World Wide Web URL at http://www.siam.org. The
114 ISBN number is 0-89871-447-8, and SIAM order code is SE09. The list
115 price for SIAM members is $31.20; the cost for nonmembers is $39.00.

154 A number of technical reports were written during the development of
155 LAPACK and published as LAPACK Working Notes, initially by Argonne
156 National Laboratory and later by the University of Tennessee. Many of
157 these reports later appeared as journal articles. Most of these working
158 notes are available in pdf and postscript form from netlib.
