1. You have successfully unbundled ARPACK and are now in the ARPACK
|
|
directory that was created for you.
|
|
|
|
2. Recent bug fixes are included in patch.tar.gz and ppatch.tar.gz
|
|
(only needed if you are using PARPACK also.) If you have not
|
|
retrieved these files, please do so and place them in the
|
|
directory right above the current directory. (They should
|
|
be in the same directory where arpack96.tar reside).
|
|
Use uncompress or gunzip to unzip the tar files, and use 'tar -xvf '
|
|
to unbundle these patches. The source codes in these patches will
|
|
overwrite those contained in arpack96.tar and parpack96.tar.
|
|
|
|
3. Upon executing the 'ls | more ' command you should see
|
|
|
|
BLAS
|
|
DOCUMENTS
|
|
EXAMPLES
|

LAPACK
|
|
README
|
|
SRC
|

UTIL
|
|
Makefile
|

ARmake.inc
|
|
ARMAKES
|
|
|
|
The following entries are directories:
|
|
|
|
ARMAKES, BLAS, DOCUMENTS, EXAMPLES, LAPACK, SRC, UTIL
|
|
|
|
The directory SRC contains the top level routines including
|
|
the highest level reverse communication interface routines
|
|
|
|
ssaupd, dsaupd - symmetric single and double precision
|
|
snaupd, dnaupd - non-symmetric single and double precision
|
|
cnaupd, cnaupd - complex non-symmetric single and double precision
|
|
|
|
The headers of these routines contain full documentation of calling
|
|
sequence and usage. Additional information is in the DOCUMENTS directory.
|
|
|
|
|
|
4. Example driver programs that illustrate all the computational modes,
|
|
data types and precisions may be found in the EXAMPLES directory.
|
|
Upon executing the 'ls EXAMPLES | more ' command you should see
|
|
|
|
BAND
|
|
COMPLEX
|
|
NONSYM
|
|
README
|
|
SIMPLE
|
|
SVD
|
|
SYM
|
|
|
|
Example programs for banded, complex, nonsymmetric, symmetric,
|
|
and singular value decomposition may be found in the directories
|
|
BAND, COMPLEX, NONSYM, SYM, SVD respectively. Look at the README
|
|
file for further information. To get started, get into the SIMPLE
|
|
directory to see example programs that illustrate the use of ARPACK in
|
|
the simplest modes of operation for the most commonly posed
|
|
standard eigenvalue problems.
|
|
|
|
The following instructions explain how to make the ARPACK library.
|
|
|
|
|
|
5. Before you can compile anything, you must first edit and correct the file
|
|
ARmake.inc. Sample ARmake.inc's can be found in the ARMAKES directory.
|
|
Edit "ARmake.inc" and change the definition "home" to the root of the
|
|
source tree (Top level of ARPACK directory)
|
|
|
|
The makefile is set up to build a self-contained library which includes
|
|
the needed BLAS 1/2/3 and LAPACK routines. If you already have the
|
|
BLAS and LAPACK libraries installed on your system you might want to
|
|
change the definition of DIRS as indicated in the ARmake.inc file.
|
|
|
|
*** NOTE *** Unless the LAPACK library on your system is version 2.0,
|
|
we strongly recommend that you install the LAPACK routines provided with
|
|
ARPACK. Note that the current LAPACK release is version 3.0; if you are
|
|
not sure which version of LAPACK is installed, pleaase compile and link
|
|
to the subset of LAPACK included with ARPACK.
|
|
|
|
|
|
6. You will also need to change the file "second.f" in the UTIL directory
|
|
to whatever is appropriate for timing on your system. The "second" routine
|
|
provided works on most workstations. If you are running on a Cray,
|
|
you can just edit the makefile in UTIL and take out the reference to
|
|
"second.o" to use the system second routine.
|
|
|
|
|
|
7. Do "make lib" in the current directory to build the standard library
|
|
"libarpack_$(PLAT).a"
|
|
|
|
8. Within DOCUMENTS directory there are three files
|
|
|
|
ex-sym.doc
|
|
ex-nonsym.doc and
|
|
ex-complex.doc
|
|
|
|
for templates on how to invoke the computational modes of ARPACK.
|
|
Also look in the README file for explanations concerning the
|
|
other documents.
