Constructor. By default, set the number of Arnoldi vectors (Lanczos vectors if the problem is symmetric) to 15. Set the solver to find the eigenvalues of largest magnitude for a non-symmetric problem).
Definition at line 455 of file arpack_solver.h.
Number of Arnoldi/Lanczos vectors. This number should be less than the size of the problem but greater than 2 times the number of eigenvalues (or n_eigenvalues if it is set) plus one.
Definition at line 242 of file arpack_solver.h.
const WhichEigenvalues ArpackSolver::AdditionalData::eigenvalue_of_interest |
Specify the eigenvalues of interest.
Definition at line 247 of file arpack_solver.h.
Specify if the problem is symmetric or not.
