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開始標準庫中已經支援rint函數了,VS 2013開始支援這一函數,修複方式

#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

安裝後測試方式

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

2.測試程式

#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]));    // 初始化疏鬆陣列      A.setFromTriplets(triplets.begin(), triplets.end());    std::cout << "A = \n" << A << std::endl;    // 一個QR分解的執行個體      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.相同檔案夾下的CMakeLists.txt

# -----------------------------------------------# Test CMake script for building against SuiteSparse#  http://code.google.com/p/suitesparse-metis-for-windows/# Created by Jose Luis Blanco (University of Almeria) 2013# Updated by jesnault ([email protected]) 2014-01-21# -----------------------------------------------PROJECT(CholmodExample)cmake_minimum_required(VERSION 2.8)# ------------------------------------------------------------------# 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.命名檔案夾src,並將上面兩個檔案放進去，並建立build檔案夾，利用cmake的configure和generate Visual Studio2013工程檔案，直接產生就可以(根據自己的FindSuiteSparse.cmake檔案的位置設定CMakeLists.txt中變數CMAKE_MODULE_PATH的位置)即可

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

#輸出結果如下b
