22 LAPACK is a library of Fortran 90 with subroutines for solving
23 the most commonly occurring problems in numerical linear algebra.
24 It is freely-available software, and is copyrighted.
26 LAPACK is available on netlib and can be obtained via the World Wide
27 Web and anonymous ftp.
29 http://www.netlib.org/lapack/
31 The distribution tar file contains the Fortran source for LAPACK and the
32 testing programs. It also contains the Fortran77
33 reference implementation of the Basic Linear Algebra Subprograms
34 (the Level 1, 2, and 3 BLAS) needed by LAPACK. However this code is
35 intended for use only if there is no other implementation of the BLAS
36 already available on your machine; the efficiency of LAPACK depends
37 very much on the efficiency of the BLAS.
41 - LAPACK can be installed with make. Configuration haev to be set in the
42 make.inc file. A make.inc.example for a Linux mahcine running GNU compilers
43 is given in the main directory. Some specific make.inc are also available in
45 - LAPACK includes also the CMAKE build. You will need to have CMAKE installed
46 on your machine (CMAKE is available at http://www.cmake.org/). CMAKE will allow
47 an easy installation on a Windows Machine
48 - Specific information to run LAPACK under Windows are available at
49 http://icl.cs.utk.edu/lapack-for-windows/lapack/
51 For further information on LAPACK please read our FAQ at
52 http://www.netlib.org/lapack/#_faq
53 A User forum is also available to help you with the LAPACK library at
54 http://icl.cs.utk.edu/lapack-forum/
61 LAPACK has been thoroughly tested, on many different
62 types of computers. The LAPACK project supports the package in the
63 sense that reports of errors or poor performance will gain immediate
64 attention from the developers. Such reports, descriptions
65 of interesting applications, and other comments should be sent by
66 electronic mail to lapack@cs.utk.edu.
68 A list of known problems, bugs, and compiler errors for LAPACK is

72 A User forum is also available to help you with the LAPACK library at
73 http://icl.cs.utk.edu/lapack-forum/
74 You can also contact directly the LAPACK team at lapack@cs.utk.edu
80 The complete package, including test code in four
81 different Fortran data types (real, complex, double precision, double
82 complex), contains some 805,000 lines of Fortran source and comments.
83 You will need approximately 33 Mbytes to read the complete tape.
84 We recommend that you run the testing. The total
85 space requirements for the testing for all four data
86 types, including the object files, is approximately 80 Mbytes.
88 A README file containing the information in this letter is located
89 in the LAPACK directory. Postscript and LaTeX versions of the Quick
90 Installation Guide are in the LAPACK/INSTALL directory, in the files
91 lawn81.tex, psfig.tex, lawn81.ps, and org2.ps. Consult the Installation
92 Guide for further details on installing the package and on what is contained
93 in each subdirectory. For complete information on the LAPACK Testing
94 please consult LAPACK Working Note 41 "Installation
101 It is highly recommended that you obtain a copy of the Third Edition of
102 the LAPACK Users' Guide published by SIAM in Winter, 1999. This Users'
103 Guide gives a detailed description of the philosophy behind LAPACK as well
104 as an explanation of its usage. The LAPACK Users' Guide can be purchased from:
105 SIAM; Customer Service; P. O. Box 7260; Philadelphia, PA 19104;
106 215-382-9800, FAX 215-386-7999. It will also be available from booksellers.
108 To order by email, send email to service@siam.org. The book is also
109 available via SIAM's World Wide Web URL at http://www.siam.org. The
110 ISBN number is 0-89871-447-8, and SIAM order code is SE09. The list
111 price for SIAM members is $31.20; the cost for nonmembers is $39.00.

151 LAPACK and published as LAPACK Working Notes, initially by Argonne
152 National Laboratory and later by the University of Tennessee. Many of
