1 .TH LAPACK 3 "2 April 1993" "LAPACK Version 1.1" "LAPACK FORTRAN LIBRARY ROUTINES"
3 LAPACK \- library of linear algebra routines
6 \fBLAPACK\fR 是一个 \fIFortran 77\fR 子程序的 transportable library ,
8 systems of linear equations, linear least squares problems, eigenvalue problems,
9 还有 singular value problems.
10 它在大部分现代的高性能计算机中可以高效地运作。
12 \fBLAPACK\fR 是 \fILINPACK\fR 和 \fIEISPACK\fR 的后继者。
14 equilibration, iterative refinement, error bounds, 和 driver routines,
15 routines for computing and re-ordering the Schur factorization,
16 还有 condition estimation routines for eigenvalue problems.
18 finding singular values and eigenvalues of bidiagonal and tridiagonal matrices
19 respectively that arise in SVD and symmetric eigenvalue problems
20 的高精度算法提高了 \fIEISPACK\fR 中标准算法的精度。
21 这些算法和软件被重新编写,在向量处理器上,高性能 ``superscalar'' 工作站上和
23 \fBLAPACK\fR 软件还附带了一个复杂的测试和时间测算套件。
27 完整的 \fBLAPACK\fR 软件包可以从 xnetlib 和 NAG 得到,也可以从 netlib 获得特定的库。

31 Xnetlib is an X-version of netlib recently developed at the University
32 of Tennessee and Oak Ridge National Laboratory. Unlike netlib, which
33 uses electronic mail to process requests for software and other text,
34 xnetlib uses an X Window graphical user interface and a socket-based
35 connection between the user's machine and the xnetlib server machine to
36 process software requests. The complete contents of LAPACK is available
37 in tar/compress format from xnetlib.
39 To receive a copy of xnetlib send the message "send xnetlib.shar from
40 xnetlib" to netlib@ornl.gov.
42 When you receive the shar file, remove the mail header, save it to a
43 file, type 'sh filename' and follow the instructions in the README
46 Alternatively, the complete LAPACK package can be
47 obtained from NAG on magnetic media for a handling charge.

60 LAPACK has been thoroughly tested, on many different
61 types of computers. The LAPACK project supports the package in the
62 sense that reports of errors or poor performance will gain immediate
63 attention from the developers. Such reports, descriptions
64 of interesting applications, and other comments should be sent by
65 electronic mail to lapack@cs.utk.edu.
67 .SH LAPACK USERS' GUIDE
69 The LAPACK Users' Guide is published by SIAM and was made available
70 May, 1992. LAPACK Users' Guide gives an informal introduction to
71 the design of the algorithms and software, summarizes the contents
72 of the package, and describes the conventions used in the software
73 and documentation, and includes complete specifications for calling
74 the routines. The LAPACK Users' Guide can be purchased from:
75 SIAM; 3600 University City Science Center; Philadelphia, PA 19104-2688;
76 215-382-9800, FAX 215-386-7999. It will also be available from
77 booksellers. The Guide costs $15.60 for SIAM members, and $19.50
78 for non-members. Please specify order code OT31 when ordering.
79 To order by email, send email to service@siam.org.
81 A list of known problems, bugs, and compiler errors for LAPACK, as
82 well as errata for the LAPACK Users' Guide and the LAPACK code itself, is
83 maintained on netlib. For a copy of this report, send email to
84 netlib@ornl.gov with a message of the form: send release_notes from
87 .SH LAPACK WORKING NOTES
89 A number of working notes were written during the
90 development of LAPACK and published as LAPACK Working Notes,
91 initially by Argonne National Laboratory and later by the University
92 of Tennessee. Many of these reports have subsequently appeared as
93 journal articles. Most of these working notes are available in postscript
94 form from netlib. To receive a list of available reports, send email to
95 netlib@ornl.gov with a message of the form: send index from lapack/lawns.
96 Otherwise, requests for copies of these working notes can be sent to
97 the following address.

109 LAPACK has been funded in part by NSF, DOE, and DARPA, with
110 developmental support from NAG Ltd., Cray Research, and many friends
111 and colleagues around the world.

128 The name of each LAPACK routine is a coded specification of
129 its function (within the very tight limits of standard Fortran 77
132 All driver and computational routines have names of the form XYYZZZ,
133 where for some driver routines the 6th character is blank.
135 The first letter, X, indicates the data type as follows:
140 Z COMPLEX*16 or DOUBLE COMPLEX
142 The next two letters, YY, indicate the type of matrix (or of the most
143 significant matrix). Most of these two-letter codes apply to both real
144 and complex matrices; a few apply specifically to one or the other.
146 The last three letters ZZZ indicate the computation performed.
147 For example, SGEBRD is a single precision routine that performs a
148 bidiagonal reduction (BRD) of a real general matrix.
