Detailed Description

Destruction routine for deleting 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_destroy_precon (  int *  options, double *  params, int *  proc_config, AZ_MATRIX *  Amat, AZ_PRECOND **  Prec )

Destroy a Komplex preconditioner. Destroys a komplex preconditioner created by the AZK_create_preconditioner function. Deletes any memory allocated by creation routine. Parameters: options  (In) Determines specific solution 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. Amat  (In) Komplex version of matrix stored as an AZ_MATRIX structure. Prec  (Out) Deleted komplex version of preconditioner stored as an AZ_PRECOND structure.
