Hello Eigen developers,
first of all thanks for your great work. We are using Eigen3 in our
simulation project [1], so I thought you might want to include in the
list of related projects.
However, there is one issue I encountered: We have to calculate the
exponential of complex eigenvalues, which are stored in a
Eigen::Array<std::complex<double> >. The elementwise exp function of the
Array class partially returned NaN's, whereas creating a wrapper for
std::exp and passing it to the unaryExp function of
Matrix<std::complex<double> > worked perfectly fine.
It seems I can't register to Bugzilla. If you create an account for me,
I'd be happy to create a bug and provide further information.
Keep up the good work!
Regards, Michael
