Flexible subspace iteration with moments for an effective contour integration-based eigensolver
Sarah Huber, Yasunori Futamura, Martin Galgon +3
Contour integration schemes are a valuable tool for the solution of difficult interior eigenvalue problems. However, the solution of many large linear systems with multiple right h…
