Gonum LAPACK Build Status Coverage Status GoDoc

This repository is no longer maintained. Development has moved to https://awesomeopensource.com/project/gonum/gonum.

A collection of packages to provide LAPACK functionality for the Go programming language (http://golang.org). This provides a partial implementation in native go and a wrapper using cgo to a c-based implementation.

Installation

  go get github.com/gonum/lapack

Install OpenBLAS:

  git clone https://github.com/xianyi/OpenBLAS
  cd OpenBLAS
  make

Then install the lapack/cgo package:

  CGO_LDFLAGS="-L/path/to/OpenBLAS -lopenblas" go install github.com/gonum/lapack/cgo

For Windows you can download binary packages for OpenBLAS at http://sourceforge.net/projects/openblas/files/

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 github.com/gonum/lapack/cgo

Packages

lapack

Defines the LAPACK API based on http://www.netlib.org/lapack/lapacke.html

lapack/lapacke

Binding to a C implementation of the lapacke interface (e.g. OpenBLAS or intel MKL)

The linker flags (i.e. path to the BLAS library and library name) might have to be adapted.

The recommended (free) option for good performance on both linux and darwin is OpenBLAS.

Issues

If you find any bugs, feel free to file an issue on the github issue tracker for gonum/gonum or gonum/netlib for the CGO implementation if the bug exists in that reposity; no code changes will be made to this repository. Other discussions should be taken to the gonum-dev Google Group.
