Abstract class definition for Anasazi Output Managers.
Anasazi's basic output manager for sending information of select verbosity levels to the appropriate ...
BasicOutputManager(int vb=Anasazi::Errors, int rootRank=0)
Default constructor.
BasicOutputManager(int vb, const Teuchos::RCP< Teuchos::FancyOStream > &fos)
Constructor with specified verbosity and formatted output stream.
Output managers remove the need for the eigensolver to know any information about the required output...
Namespace Anasazi contains the classes, structs, enums and utilities used by the Anasazi package.
