ArnoldiEigenvalueSolverSolve(DoubleSymmetricMatrix, DoubleSymmetricMatrix, ArnoldiEigenvalueOptions) Method

Solve the generalized egivenvalue problem Ax = Mx(lambda) Where A is sparse symmetric and M is sparse symmetric semi position definite. Solve is accomplished using a shift and invert spectral transformation and implicitly restarted Arnoldi iteration.
