Win10 VS2013 suitesparse-metis-for-windows 1.3.1

suitesparse-metis-for-windows 1.3.1 Installation package with Suitesparse 4.5.1, Metis 5.1.0 and Lapack 3.4.1

The Suitesparse package on GitHub is suitable for installation in Windows Https://github.com/jlblancoc/suitesparse-metis-for-windows with detailed installation instructions, But there will be a bug.

问题1：metis/GKlib/gk_arch.hThere is a bug in the standard library since C++11 has already supported the Rint function, VS 2013 began to support this function, the repair method

#ifdef __msc__ /*  */#if#define rint (x) ((int) ((x) +0.5)  #endif/*   */#ifndef INFINITY#define INFINITY flt_max#endif#endif  #endif

Post-Installation test methods

1. setting in Environment variablesSuiteSparse_DIR位置是SuiteSoarse的安装位置，例如C:\Program Files (x86)\Suitesparse

2. Test procedures

#include <iostream>#include"Eigen/eigen"#include"Eigen/spqrsupport"using namespace Eigen;intMain () {Sparsematrix<Double> A (4,4); Std::vector< Triplet <Double> >triplets; //Initialize non-0 elements    intr[3] = {0,1,2 }; intc[3] = {1,2,2 }; Doubleval[3] = {6.1,7.2,8.3 };  for(inti =0; I <3; ++i) triplets.push_back (Triplet<Double>(R[i], c[i], val[i])); //Initializing sparse matricesa.setfromtriplets (Triplets.begin (), Triplets.end ()); Std::cout<<"A = \ n"<< A <<Std::endl; //An example of a QR decompositionSPQR < Sparsematrix <Double> >QR; //Calculate DecompositionQr.compute (A); //ask for a x = bVECTOR4D B (1,2,3,4); VECTOR4D x=Qr.solve (b); Std::cout<<"x = \ n"<<x; Std::cout<<"A x = \ n"<< A *x;    GetChar (); Return0;}

2. CMakeLists.txt under the same folder

3. Name the folder SRC, and put the above two files in, and create a build folder, using CMake configure and generate Visual Studio2013 engineering files, directly generated can ( Set the position of the variable Cmake_module_path in the CMakeLists.txt according to the location of your Findsuitesparse.cmake file)

4. If you do not use the CMake tool, remember to set the installation location of the Lapack and Suitesparse libraries in the project properties of VS, link to the following libraries

 c:\program files (x86) \suitesparse\lib64\metisd.libc:\program files (x86) \ Suitesparse\lib\suitesparseconfigd.libc:\program files (x86) \suitesparse\lib\libamdd.libc:\program files (x86) \ Suitesparse\lib\libbtfd.libc:\program files (x86) \suitesparse\lib\libcamdd.libc:\program files (x86) \Suitesparse\ Lib\libccolamdd.libc:\program files (x86) \suitesparse\lib\libcolamdd.libc:\program files (x86) \suitesparse\lib\ Libcholmodd.libc:\program files (x86) \suitesparse\lib\libcxsparsed.libc:\program files (x86) \suitesparse\lib\ Libklud.libc:\program files (x86) \suitesparse\lib\libldld.libc:\program files (x86) \suitesparse\lib\ Libumfpackd.libc:\program files (x86) \suitesparse\lib\libspqrd.libc:\program files (x86) \suitesparse\lib\lapack_ Blas_windows\libblas.libc:\program Files (x86) \suitesparse\lib\lapack_blas_windows\ Liblapack.libkernel32.libuser32.libgdi32.libwinspool.libshell32.libole32.liboleaut32.libuuid.libcomdlg32.lib
