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

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