Improving the convergence of iterative methods

Jan Zítko (1983)

Aplikace matematiky

Similarity:

The author considers the operator equation x = T x + b . Methods for acceleration of convergence of the iterative process x n + 1 ) = T x n + b are investigated.

The method of fictitious right-hand sides

Milan Práger (1984)

Aplikace matematiky

Similarity:

The paper deals with the application of a fast algorithm for the solution of finite-difference systems for boundary-value problems on a standard domain (e.g. on a rectangle) to the solution of a boundary-value problem on a domain of general shape contained in the standard domain. A simple iterative procedure is suggested for the determination of fictitious right-hand sides for the system on the standard domain so that its solution is the desired one. Under the assumptions that are usual...
