suitesparse-metis-for-windows 1.3.1 安装包内附SuiteSparse 4.5.1, Metis 5.1.0和 lapack 3.4.1

Github上面由整理好的suitesparse包适合在Windows安装 https://github.com/jlblancoc/suitesparse-metis-for-windows，并附有详细的安装指导，但是会有一点bug

问题1：metis/GKlib/gk_arch.h中有个bug，从C++11开始标准库中已经支持rint函数了,VS 2013开始支持这一函数,修复方式

#ifdef __MSC__
/* MSC does not have rint() function */
#if (_MSC_VER < 1800)　　/*visual studio 2013编译器版本*/
 #define rint(x) ((int)((x)+0.5))
#endif

/* MSC does not have INFINITY defined */
#ifndef INFINITY
#define INFINITY FLT_MAX
#endif
#endif
#endif

安装后测试方式

1.在环境变量中设置SuiteSparse_DIR位置是SuiteSoarse的安装位置，例如C:\Program Files (x86)\Suitesparse

2.测试程序

#include <iostream>
#include "Eigen/Eigen"
#include "Eigen/SPQRSupport"
using namespace Eigen;
int main() {

    SparseMatrix < double > A(4, 4);
    std::vector < Triplet < double > > triplets;

    // 初始化非零元素
    int r[3] = { 0, 1, 2 };
    int c[3] = { 1, 2, 2 };
    double val[3] = { 6.1, 7.2, 8.3 };
    for (int i = 0; i < 3; ++i)
        triplets.push_back(Triplet < double >(r[i], c[i], val[i]));

    // 初始化稀疏矩阵
    A.setFromTriplets(triplets.begin(), triplets.end());
    std::cout << "A = \n" << A << std::endl;

    // 一个QR分解的实例
    SPQR < SparseMatrix < double > > qr;
    // 计算分解
    qr.compute(A);
    // 求一个A x = b
    Vector4d b(1, 2, 3, 4);
    Vector4d x = qr.solve(b);
    std::cout << "x = \n" << x;
    std::cout << "A x = \n" << A * x;

    getchar();
    return 0;
}

2.相同文件夹下的CMakeLists.txt

set(SuiteSparse_USE_LAPACK_BLAS ON)

        #set(SuiteSparse_VERBOSE ON)

        include_directories(${SuiteSparse_INCLUDE_DIRS})
else()
        message(STATUS "Find SuiteSparse : include(${USE_SuiteSparse})")
        include(${USE_SuiteSparse})
endif()
MESSAGE(STATUS "SuiteSparse_LIBS: ${SuiteSparse_LIBRARIES}")
# ------------------------------------------------------------------

ADD_EXECUTABLE(cholmod-test cholmod-test.c)
TARGET_LINK_LIBRARIES(cholmod-test ${SuiteSparse_LIBRARIES})

3.命名文件夹src,并将上面两个文件放进去，并创建build文件夹，利用cmake的configure和generate Visual Studio2013工程文件，直接生成就可以(根据自己的FindSuiteSparse.cmake文件的位置设置CMakeLists.txt中变量CMAKE_MODULE_PATH的位置)即可

4.如果不使用cmake工具，记得在VS的工程属性中设置lapack和suitesparse库的安装位置，链接如下库即可
