Member Function Documentation

std::pair< Real, Real > MAST::SlepcEigenSolver::get_eigenpair ( unsigned int  i,
libMesh::NumericVector< Real > &  eig_vec,
libMesh::NumericVector< Real > *  eig_vec_im = libmesh_nullptr 
)
virtual

This function returns the real and imaginary part of the ith eigenvalue and copies the respective eigenvector to the solution vector.

Note that also in case of purely real matrix entries the eigenpair may be complex values.
