Win10 VS2013 suitesparse-metis-for-windows 1.3.1

suitesparse-metis-for-windows 1.3.1 安裝包內附SuiteSparse 4.5.1, Metis 5.1.0和 lapack 3.4.1

Github上面由整理好的suitesparse包適合在Windows安裝 https://github.com/jlblancoc/suitesparse-metis-for-windows，並附有詳細的安裝指導，但是會有一點bug

問題1：metis/GKlib/gk_arch.h中有個bug，從C++11開始標准庫中已經支持rint函數了,VS 2013開始支持這一函數,修復方式

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

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

安裝后測試方式

1.在環境變量中設置SuiteSparse_DIR位置是SuiteSoarse的安裝位置，例如C:\Program Files (x86)\Suitesparse

2.測試程序

#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]));

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

    // 一個QR分解的實例  
    SPQR < SparseMatrix < double > > qr;
    // 計算分解  
    qr.compute(A);
    // 求一個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.相同文件夾下的CMakeLists.txt

# ------------------------------------------------------------------
# Detect SuiteSparse libraries:
# If not found automatically, set SuiteSparse_DIR in CMake to the 
# directory where SuiteSparse was built.
# ------------------------------------------------------------------
LIST(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/../../cmakemodule/") # Add the directory where FindSuiteSparse.cmake module can be found.

set(SuiteSparse_USE_LAPACK_BLAS ON)
find_package(SuiteSparse QUIET NO_MODULE)  # 1st: Try to locate the *config.cmake file.
if(NOT SuiteSparse_FOUND)
        #set(SuiteSparse_VERBOSE ON)
        find_package(SuiteSparse REQUIRED) # 2nd: Use FindSuiteSparse.cmake module
        include_directories(${SuiteSparse_INCLUDE_DIRS})
else()
        message(STATUS "Find SuiteSparse : include(${USE_SuiteSparse})")
        include(${USE_SuiteSparse})
endif()
MESSAGE(STATUS "SuiteSparse_LIBS: ${SuiteSparse_LIBRARIES}")
# ------------------------------------------------------------------
#   End of SuiteSparse detection
# ------------------------------------------------------------------


# ------------------------------------------------------------------
# Declare an example program:
# ------------------------------------------------------------------
ADD_EXECUTABLE(cholmod-test cholmod-test.c)
TARGET_LINK_LIBRARIES(cholmod-test ${SuiteSparse_LIBRARIES})

3.命名文件夾src,並將上面兩個文件放進去，並創建build文件夾，利用cmake的configure和generate Visual Studio2013工程文件，直接生成就可以(根據自己的FindSuiteSparse.cmake文件的位置設置CMakeLists.txt中變量CMAKE_MODULE_PATH的位置)即可

4.如果不使用cmake工具，記得在VS的工程屬性中設置lapack和suitesparse庫的安裝位置，鏈接如下庫即可
