# Gonum BLAS
[](https://pkg.go.dev/gonum.org/v1/gonum/blas)
[](https://godocs.io/gonum.org/v1/gonum/blas)
A collection of packages to provide BLAS functionality for the [Go programming
language](http://golang.org)
## Installation
```sh
go get gonum.org/v1/gonum/blas/...
```
## Packages
### blas
Defines [BLAS API](http://www.netlib.org/blas/blast-forum/cinterface.pdf) 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.
```Go
package main
import (
"fmt"
"gonum.org/v1/gonum/blas/blas64"
)
func main() {
v := blas64.Vector{Inc: 1, Data: []float64{1, 1, 1}}
v.N = len(v.Data)
fmt.Println("v has length:", blas64.Nrm2(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.
