./math/blas64, Reference Basic Linear Algebra System with 64 bit indices

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 3.12.0, Package name: blas64-3.12.0, Maintainer: thomas.orgis

The BLAS (Basic Linear Algebra Subprograms) are high quality "building
block" routines for performing basic vector and matrix
operations. Level 1 BLAS do vector-vector operations, Level 2 BLAS do
matrix-vector operations, and Level 3 BLAS do matrix-matrix
operations. Because the BLAS are efficient, portable, and widely
available, they're commonly used in the development of high quality
linear algebra software, LINPACK and LAPACK for example.

This package contains the Fortran 77 reference implementation of BLAS.

Log message:
math/{lapack*,cblas*}: update netlib BLAS to 3.12.0

This drops the static libraries along with the custom patches for those. Also,
the hack of linking CBLAS as Fortran library as opposed to C is gone. If this
breaks some NetBSD install, it should be investigated and fixed properly.

The only patch now is one unified one I already submitted for inclusion
upstream. Maybe soon we can drop any patches. Yay!

Here is a list of upstream changes:

LAPACK 3.12.0: What’s new

This is a major release and also addressing multiple bug fixes.
Dynamic Mode Decomposition (DMD)

    xGEDMD computes the Dynamic Mode Decomposition (DMD) for a pair of
    data snapshot matrices. For the input matrices X and Y such that Y =
    A*X with an inaccessible matrix A, xGEDMD computes a certain number
    of Ritz pairs of A using the standard Rayleigh-Ritz extraction from
    a subspace of range(X) that is determined using the leading left
    singular vectors of X. Optionally, xGEDMD returns the residuals of
    the computed Ritz pairs, the information needed for a refinement of
    the Ritz vectors, or the eigenvectors of the Exact DMD.

    xGEDMDQ does the same as xGEDMD but uses a QR factorization based
    compression of the data.

    See: Z. Drmac: A LAPACK implementation of the Dynamic Mode
    Decomposition I. Technical report. AIMDyn Inc. and LAPACK Working
    Note 298.

Truncated QR with Column Pivoting

    The routine computes a truncated (rank K) or full rank Householder
    QR factorization with column pivoting of a real M-by-N matrix A
    using Level 3 BLAS.

    The truncation criteria (i.e. when to stop the factorization) can
    be any of the following: (1) The input parameter KMAX, the maximum
    number of columns KMAX to factorize; (2) The input parameter ABSTOL,
    the absolute tolerance for the maximum column 2-norm of the residual
    matrix R22(K); (3) The input parameter RELTOL, the tolerance for the
    maximum column 2-norm matrix of the residual matrix R22(K) divided by
    the maximum column 2-norm of the original matrix A, which is equal
    to abs(R(1,1)). The algorithm stops when any of these conditions is
    first satisfied, otherwise the whole matrix A is factorized.

Reciprocal Scaling of complex vectors

    [C/Z]RSCL multiplies an n-element complex vector x by the complex
    scalar 1/a. This is done without overflow or underflow as long as
    the final result x/a does not overflow or underflow.

    of a complex number", Weslley da Silva Pereira,
