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.
