Preconditioned fast solvers for large linear systems with specific sparse and/or Toeplitz-like structures and applications

F Durastante - 2017 - irinsubria.uninsubria.it
In this thesis, the design of the preconditioners we propose starts from applications instead
of treating the problem in a completely general way. The reason is that not all types of linear …
