Approximate
factoring and inverse for preconditioning
In the so-called algebraic approach to preconditioning
large and sparse linear systems, there are roughly two
options:
- Approximate factoring such as ILU
- Approximate inverse
In this talk I will present some preliminary ideas for
approximate factoring.
