Hi all,

BLAS Levels 1,2 and 3 are now available for testing
at https://github.com/barnex/gsl

cheers,

BLAS (Basic Linear Algebra Subprograms) level 1 for float32 and
float64 types. Modified Givens rotation functions aren't implemented.

All functions have Go implementation and AMD64 assembler
implementation to, so they run fast on AMD64 (especially on Nehalem,
Sandy Bridge and newer processors) and rather slow on other platforms
(especially if compiled without -B flag).

    IMO, it's worth mentioning in the README that the package's license is
    GPL3+ (because that's rather uncommon for Go F/OSS packages).

    At gonum, we have a wrapper to cblas (github.com/gonum/blas/cblas), and a
    partial blas implementation in pure go (github.com/gonum/blas/goblas). Go
    needs to hoist bounds checking and do some autovectorization before the Go
    code is truly competitive, but the go implementation is certainly easier to
    use, especially when you want to share a binary with someone else. The two
    blas wrappers satisfy the same interface, so they can be swapped in and out
    for one another. See
    https://godoc.org/github.com/gonum/matrix/mat64#Register for an example.

    I've updated the README to indicate that the project inherits the GPL from
    GSL, but the Go wrapper files themselves are BSD and may be used to wrap
    other BLAS implementations.

    Note that the GPL is inherited because this package incorporates GSL's
    CBLAS code. You can "go get" the package without having a BLAS
    installation. The resulting binaries will be statically linked!

    Relatedly, is anyone working on an optimization library? I could see
    how BLAS implementations would come first, but thought I'd ask as it's
    on my mind.
    We also now have the start of an optimization library at
    github.com/gonum/optimize
