Re: [eigen] Block sparse matrices and std vector compilation error

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]

I am not sure about the problem.

It compiles with g++ 4.8.2

It is a good idea to define use typedef or some other construction
to further simplify the program. For example the following compiles
as well:
------------------------------------------
#include <iostream>
#include <Eigen/Dense>
#include <Eigen/Sparse>

typedef Eigen::SparseMatrix<double, Eigen::ColMajor> MyMatrix;

int main(int argc, char** argv)
{
  MyMatrix A_sparse(10, 10);
  std::vector<Eigen::Block<MyMatrix> > sparse_block_vector;
  Eigen::Block<MyMatrix> sparse_block = A_sparse.block(0, 0, 5, 5);
  sparse_block_vector.push_back(sparse_block);
}
-----------------------------------
Best,

  Mathieu

Dear all,


I am interested in storing block sparse matrices in std vectors but get a compiling error, the error does not happen for dense matrices. I am using Eigen 3.2.2 with gcc version 4.6.3


Here is small code to reproduce the problem

#include <iostream>
#include <Eigen/Dense>
#include <Eigen/Sparse>

int main(int argc, char** argv){

  Eigen::SparseMatrix<double, Eigen::ColMajor> A_sparse(10, 10);
  std::vector< Eigen::Block<Eigen::SparseMatrix<double, Eigen::ColMajor> > > sparse_block_vector;
  Eigen::Block<Eigen::SparseMatrix<double, Eigen::ColMajor> > sparse_block = A_sparse.block(0, 0, 5, 5);
  sparse_block_vector.push_back(sparse_block);

}

And the error output
