Enumeration types for the selection rule of eigenvalues.
The enumeration to report the status of computation.
| Enumerator |
|---|
| SUCCESSFUL |
Computation was successful.
|
| NOT_COMPUTED |
Used in eigen solvers, indicating that computation has not been conducted. Users should call the compute() member function of solvers.
|
| NOT_CONVERGING |
Used in eigen solvers, indicating that some eigenvalues did not converge. The compute() function returns the number of converged eigenvalues.
|
| NUMERICAL_ISSUE |
Used in Cholesky decomposition, indicating that the matrix is not positive definite.
|
Definition at line 17 of file CompInfo.h.
The enumeration to specify the mode of generalized eigenvalue solver.
| Enumerator |
|---|
| GEIGS_CHOLESKY |
Using Cholesky decomposition to solve generalized eigenvalues.
|
| GEIGS_REGULAR_INVERSE |
Regular inverse mode for generalized eigenvalue solver.
|
| GEIGS_SHIFT_INVERT |
Shift-and-invert mode for generalized eigenvalue solver.
|
| GEIGS_BUCKLING |
Buckling mode for generalized eigenvalue solver.
|
| GEIGS_CAYLEY |
Cayley transformation mode for generalized eigenvalue solver.
|
Definition at line 17 of file GEigsMode.h.
The enumeration of selection rules of desired eigenvalues.
| Enumerator |
|---|
| LARGEST_MAGN |
Select eigenvalues with largest magnitude. Magnitude means the absolute value for real numbers and norm for complex numbers. Applies to both symmetric and general eigen solvers.
|
| LARGEST_REAL |
Select eigenvalues with largest real part. Only for general eigen solvers.
|
| LARGEST_IMAG |
Select eigenvalues with largest imaginary part (in magnitude). Only for general eigen solvers.
|
| LARGEST_ALGE |
Select eigenvalues with largest algebraic value, considering any negative sign. Only for symmetric eigen solvers.
|
| SMALLEST_MAGN |
Select eigenvalues with smallest magnitude. Applies to both symmetric and general eigen solvers.
|
| SMALLEST_REAL |
Select eigenvalues with smallest real part. Only for general eigen solvers.
|
| SMALLEST_IMAG |
Select eigenvalues with smallest imaginary part (in magnitude). Only for general eigen solvers.
|
| SMALLEST_ALGE |
Select eigenvalues with smallest algebraic value. Only for symmetric eigen solvers.
|
| BOTH_ENDS |
Select eigenvalues half from each end of the spectrum. When nev is odd, compute more from the high end. Only for symmetric eigen solvers.
