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.

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.
