krypy.recycling.generators
- generators for deflation vector candidates¶

class
krypy.recycling.generators.
RitzExtremal
(max_vectors=inf)¶ Bases:
krypy.recycling.generators._RitzSubsetsGenerator
Successively returns the extremal Ritz values.
For self-adjoint problems, the indices of the minimal negative, maximal negative, minimal positive and maximal positive Ritz values are returned.
For non-self-adjoint problems, only the indices of the Ritz values of smallest and largest magnitude are returned.

(max_vectors=inf)¶ Bases:
