Detailed Description

Abstract class to construct preconditioners from a matrix in Epetra_CsrFormat.

This class implementents all public methods of the parent class LinearOperator, and additionally introduce the following public methods"

SetRowMatrix to specify the matrix in Epetra_CsrMatrix format
SetParameterList to specify the list of parameter to be used in the preconditioner
Compute do all the operator to compute the preconditioner. This method assert that the parameter are set correctly and then it calls the protected abstract method myCompute.

Concrete instances of the RowMatrixPreconditioner class should implement the protected method myCompute.
