Library of subroutines to solve eigenvalue problems
Branch: CURRENT,
Version: 96nb2,
Package name: arpack96nb2,
Maintainer: baconARPACK is a collection of Fortran77 subroutines designed to solve large
scale eigenvalue problems.
The package is designed to compute a few eigenvalues and corresponding
eigenvectors of a general n by n matrix A. It is most appropriate for large
sparse or structured matrices A where structured means that a matrixvector
product w < Av requires order n rather than the usual order n**2 floating
point operations. This software is based upon an algorithmic variant of the
Arnoldi process called the Implicitly Restarted Arnoldi Method (IRAM). When
the matrix A is symmetric it reduces to a variant of the Lanczos process
called the Implicitly Restarted Lanczos Method (IRLM). These variants may be
viewed as a synthesis of the Arnoldi/Lanczos process with the Implicitly
Shifted QR technique that is suitable for large scale problems. For many
standard problems, a matrix factorization is not required. Only the action
of the matrix on a vector is needed. ARPACK software is capable of solving
large scale symmetric, nonsymmetric, and generalized eigenproblems from
significant application areas. The software is designed to compute a few (k)
eigenvalues with user specified features such as those of largest real part
or largest magnitude. Storage requirements are on the order of n*k locations.
No auxiliary storage is required. A set of Schur basis vectors for the desired
kdimensional eigenspace is computed which is numerically orthogonal to working
precision. Numerically accurate eigenvectors are available on request.
Important Features:
o Reverse Communication Interface.
o Single and Double Precision Real Arithmetic Versions for Symmetric,
Nonsymmetric, Standard or Generalized Problems.
o Single and Double Precision Complex Arithmetic Versions for Standard
or Generalized Problems.
o Routines for Banded Matrices  Standard or Generalized Problems.
o Routines for The Singular Value Decomposition.
o Example driver routines that may be used as templates to implement
numerous ShiftInvert strategies for all problem types, data types
and precision.

Log message:
Remove math/arpack successor math/arpackng
No arpack release has been published by Rice University for many years, and
arpackng aims to provide a common repository of community fixes with a
testsuite.

Log message:
all: migrate homepages from http to https
pkglint r network only "migrate"
As a sideeffect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
Correct the default value of BUILDLINK_DEPMETHOD.arpack
Since arpack installs a dynamic library, its BUILDLINK_DEPMETHOD
shouldn't be set to "build" by default.
Bump PKGREVISION of octave for its runtime dependency change.
