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

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