OpenBLAS
:下载
http://netix.dl.sourceforge.net/project/openblas/v0.2.15/OpenBLAS-v0.2.15-Win64-int32.zip
解压到D:\Develop\OpenBLAS\OpenBLAS-v0.2.15-Win64-int32\bin
http://netix.dl.sourceforge.net/project/openblas/v0.2.15/mingw64_dll.zip
解压到D:\Develop\OpenBLAS\OpenBLAS-v0.2.15-Win64-int32\bin

NetLib
：maven 配置
<dependency>
<groupId>com.github.fommil.netlib</groupId>
<artifactId>all</artifactId>
<version>1.1.2</version>
<type>pom</type>
</dependency>
：需要
libblas3.dll(拷贝libopenblas.dll为其名)
liblapack3.dll(拷贝libopenblas.dll为其名)
libgfortran-1-3.dll(mingw64_dll.zip)
libquadmath-0.dll(mingw64_dll.zip)
libgcc_s_seh-1.dll(mingw64_dll.zip)
：测试NetLib依赖安装

package com.bbw5.netlib;


import com.github.fommil.netlib.*;

public class NetLibTest {

	public static void main(String[] args) {
		NativeRefBLAS.getInstance();
		NativeRefLAPACK.getInstance();
		NativeRefARPACK.getInstance();
	}

}
