20 LAPACK is a library of Fortran 90 with subroutines for solving
21 the most commonly occurring problems in numerical linear algebra.
22 It is freely-available software, and is copyrighted.
24 LAPACK is available on netlib and can be obtained via the World Wide
25 Web and anonymous ftp.
27 http://www.netlib.org/lapack/
29 The distribution tar file contains the Fortran source for LAPACK and the
30 testing programs. It also contains the Fortran77
31 reference implementation of the Basic Linear Algebra Subprograms
32 (the Level 1, 2, and 3 BLAS) needed by LAPACK. However this code is
33 intended for use only if there is no other implementation of the BLAS
34 already available on your machine; the efficiency of LAPACK depends
35 very much on the efficiency of the BLAS.
37 The complete package, including test code in four
38 different Fortran data types (real, complex, double precision, double
39 complex), contains some 805,000 lines of Fortran source and comments.
40 You will need approximately 33 Mbytes to read the complete tape.
41 We recommend that you run the testing. The total
42 space requirements for the testing for all four data
43 types, including the object files, is approximately 80 Mbytes.
45 A README file containing the information in this letter is located
46 in the LAPACK directory. Postscript and LaTeX versions of the Quick
47 Installation Guide are in the LAPACK/INSTALL directory, in the files
48 lawn81.tex, psfig.tex, lawn81.ps, and org2.ps. Consult the Installation
49 Guide for further details on installing the package and on what is contained
50 in each subdirectory. For complete information on the LAPACK Testing
51 please consult LAPACK Working Note 41 "Installation
54 It is highly recommended that you obtain a copy of the Third Edition of
55 the LAPACK Users' Guide published by SIAM in Winter, 1999. This Users'
56 Guide gives a detailed description of the philosophy behind LAPACK as well
57 as an explanation of its usage. The LAPACK Users' Guide can be purchased from:
58 SIAM; Customer Service; P. O. Box 7260; Philadelphia, PA 19104;
59 215-382-9800, FAX 215-386-7999. It will also be available from booksellers.
61 To order by email, send email to service@siam.org. The book is also
62 available via SIAM's World Wide Web URL at http://www.siam.org. The
63 ISBN number is 0-89871-447-8, and SIAM order code is SE09. The list
64 price for SIAM members is $31.20; the cost for nonmembers is $39.00.
66 To view an HTML version of the Users' Guide please refer to the URL

70 The Fortran95 interface to LAPACK is available, as well as an f2c'ed
71 version of LAPACK, and a C++ version of a subset of LAPACK routines.

84 LAPACK has been thoroughly tested, on many different
85 types of computers. The LAPACK project supports the package in the
86 sense that reports of errors or poor performance will gain immediate
87 attention from the developers. Such reports, descriptions
88 of interesting applications, and other comments should be sent by
89 electronic mail to lapack@cs.utk.edu.
91 A list of known problems, bugs, and compiler errors for LAPACK is
93 http://www.netlib.org/lapack/release_notes.html
95 A number of technical reports were written during the development of
96 LAPACK and published as LAPACK Working Notes, initially by Argonne
97 National Laboratory and later by the University of Tennessee. Many of
98 these reports later appeared as journal articles. Most of these working
99 notes are available in pdf and postscript form from netlib.
