Detailed Description

Adapter class for creating a generalized operator to apply to an Anasazi::EpetraOpMultiVec.

This class will apply the operation $A^{-1}M$ [default] or $AM$ , for the Apply method of the Epetra_Operator / Anasazi::Operator. The Anasazi::EpetraOpMVGenOp operator is useful when spectral transformations are used within eigensolvers. For instance, $A^{-1}M$ is a shift and invert spectral transformation commonly used with Anasazi::BlockKrylovSchur to compute the smallest-magnitude eigenvalues for the eigenproblem $Ax = \lambda Mx$ .

Note:: The Epetra package performs double-precision arithmetic, so the use of Epetra with Anasazi will only provide a double-precision eigensolver.
