Abstract
The nonsymmetric Lanczos method has recently received attention as a model reduction technique for large-scale systems. However, the Lanczos method may generate an unstable partial realization for a given stable system. To remedy this situation, inexpensive implicit restarts are developed to stabilize a Lanczos generated model.
