Class for standard eigenvalue problem in shift and invert mode Matrix-vector product provided: y <- inv(A-sigma*Id) * x.
Public Functions
-
ARInterfaceStdShf(const MA_ &matA, const K_ sigma)#
-
A_s constructor for standard problem in shift and invert mode.
sigma is the shift. The matrix A-sigma*Id is computed internally and stored.
-
ARInterfaceStdShf(const MA_ &matAsI)#
-
AsI constructor for standard problem in shift and invert mode.
The input matrix matAsI corresponds to A-sigma*Id and must be provided by the user.
