suitesparse-metis-for-windows 1.3.1 安置包内附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安置 https://github.com/jlblancoc/suitesparse-metis-for-windows，并附有详细的安置指导，但是会有一点bug
问题1：metis/GKlib/gk_arch.h中有个bug，从C++11开始标准库中已经撑持rint函数了,VS 2013开始撑持这一函数,修复方法
#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
安置后测试方法
1.在环境变量中设置SuiteSparse_DIR位置是SuiteSoarse的安置位置，例如C:\Program Files (x86)\Suitesparse
2.测试措施
#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分化的实例 SPQR < SparseMatrix < double > > qr; // 计算分化 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.不异文件夹下的CMakeLists.txt
