问题原因:Eigen3的bug
1 template <typename MatrixType> 2 class LinearSolverEigen: public LinearSolver<MatrixType> 3 { 4 public: 5 typedef Eigen::SparseMatrix<double,Eigen::ColMajor> SparseMatrix; 6 typedef Eigen::Triplet<double> Triplet; 7 typedef Eigen::PermutationMatrix<Eigen::Dynamic,Eigen::Dynamic,SparseMatrix::Index> PermutationMatrix;
改为
1 template <typename MatrixType> public LinearSolver<MatrixType> 3 { public: SparseMatrix; double> Triplet; 8 typedef Eigen::PermutationMatrix<Eigen::Dynamic,int> PermutationMatrix; 9 /**
