Detailed Description

Creation routines for constructing a preconditioner for a Komplex matrix.

KOMPLEX is an add-on module to AZTEC that allows users to solve complex-valued linear systems. As such, all Aztec preconditioners are available. To learn how to set preconditioner options, please see the Aztec 2.1 User Guide.

Function Documentation

void AZK_create_precon (  int *  options, double *  params, int *  proc_config, double *  x, double *  b, AZ_MATRIX *  Amat, AZ_PRECOND **  Prec )

Create a Preconditioner for a Komplex matrix. Constructs a preconditioner for a Komplex matrix Amat. All preconditioning options available in Aztec are supported. Parameters: options  (In) Determines specific preconditioner method and other parameters. params  (In) Drop tolerance and convergence tolerance info. proc_config  (In) Machine configuration. proc_config[AZ_node] is the node number. proc_config[AZ_N_procs] is the number of processors. x  (In/Out) Komplex version of initial guess and solution. May be modified depending on preconditioner options. b  (In/Out) Komplex version of RHS. May be modified depending on preconditioner options. Amat  (In) Komplex version of matrix stored as an AZ_MATRIX structure. Prec  (Out) Preconditioner for Amat stored as an AZ_PRECOND structure.
