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.
34 The distribution tar file contains the Fortran
source for LAPACK and the
35 testing programs. It also contains the Fortran77
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
50 an easy installation on a Windows Machine
51 - Specific information to run LAPACK under Windows are available at

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.

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

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.
