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

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