Ubuntu
eigen3 package

The Eigen3 library can not compute the eigenvectors together with the eigenvalues

Asked by DT

Hi!, I'm using ubuntu 16.04 and ROS-Kinetic branches,

I have cloned elevation mapping package from https://github.com/ethz-asl/elevation... .

The problem is when I launching the elevation mapping packages at first I get some fused elevation mapping data then after sometimes I get an exception error from the Egien3 library which says:

elevation_mapping: /usr/include/eigen3/Eigen/src/Eigenvalues/EigenSolver.h:347: Eigen::EigenSolver<_MatrixType>::EigenvectorsType Eigen::EigenSolver<_MatrixType>::eigenvectors() const [with _MatrixType = Eigen::Matrix<double, 2,="" 2="">; Eigen::EigenSolver<_MatrixType>::EigenvectorsType = Eigen::Matrix<std::complex<double>, 2, 2>; typename Eigen::NumTraits<typename derived::scalar="">::Real = double]: Assertion `m_eigenvectorsOk && "The eigenvectors have not been computed together with the eigenvalues."' failed.

And It crashes.

Is there any way to fix this problem?
