Gonum BLAS 
A collection of packages to provide BLAS functionality for the Go programming language
Installation
go get gonum.org/v1/gonum/blas/...
BLAS C-bindings
If you want to use OpenBLAS, install it in any directory:
git clone https://github.com/xianyi/OpenBLAS
cd OpenBLAS
make
The blas/cgo package provides bindings to C-backed BLAS packages. blas/cgo needs the CGO_LDFLAGS
environment variable to point to the blas installation. More information can be found in the
cgo command documentation.
Then install the blas/cgo package:
CGO_LDFLAGS="-L/path/to/OpenBLAS -lopenblas" go install gonum.org/v1/netlib/blas
For Windows you can download binary packages for OpenBLAS at SourceForge.
If you want to use a different BLAS package such as the Intel MKL you can
adjust the CGO_LDFLAGS variable:
CGO_LDFLAGS="-lmkl_rt" go install gonum.org/v1/netlib/blas
On OS X the easiest solution is to use the libraries provided by the system:
CGO_LDFLAGS="-framework Accelerate" go install gonum.org/v1/netlib/blas
Packages
blas
Defines BLAS API split in several interfaces.
blas/gonum
Go implementation of the BLAS API (incomplete, implements the float32 and float64 API).
blas/blas64 and blas/blas32
Wrappers for an implementation of the double (i.e., float64) and single (float32)
precision real parts of the BLAS API.
package main
import (
"fmt"
"gonum.org/v1/gonum/blas/blas64"
)
func main() {
v := blas64.Vector{Inc: 1, Data: []float64{1, 1, 1}}
fmt.Println("v has length:", blas64.Nrm2(len(v.Data), v))
}
blas/cblas128 and blas/cblas64
Wrappers for an implementation of the double (i.e., complex128) and single (complex64)
precision complex parts of the blas API.
Currently blas/cblas64 and blas/cblas128 require gonum.org/v1/netlib/blas.
