EigenvalueDecomposition:: (10 methods):
tred2()
tql2()
orthes()
cdiv()
hqr2()
__construct()
getV()
getRealEigenvalues()
getImagEigenvalues()
getD()
Class: EigenvalueDecomposition - X-Ref
| tred2() X-Ref |
| Symmetric Householder reduction to tridiagonal form. |
| tql2() X-Ref |
| Symmetric tridiagonal QL algorithm. This is derived from the Algol procedures tql2, by Bowdler, Martin, Reinsch, and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutine in EISPACK. |
| orthes() X-Ref |
| Nonsymmetric reduction to Hessenberg form. This is derived from the Algol procedures orthes and ortran, by Martin and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutines in EISPACK. |
| cdiv($xr, $xi, $yr, $yi) X-Ref |
| Performs complex division. |
| hqr2() X-Ref |
| Nonsymmetric reduction from Hessenberg to real Schur form. Code is derived from the Algol procedure hqr2, by Martin and Wilkinson, Handbook for Auto. Comp., Vol.ii-Linear Algebra, and the corresponding Fortran subroutine in EISPACK. |
| __construct($Arg) X-Ref |
| Constructor: Check for symmetry, then construct the eigenvalue decomposition param: A Square matrix return: Structure to access D and V. |
| getV() X-Ref |
| Return the eigenvector matrix return: V |
| getRealEigenvalues() X-Ref |
| Return the real parts of the eigenvalues return: real(diag(D)) |
| getImagEigenvalues() X-Ref |
| Return the imaginary parts of the eigenvalues return: imag(diag(D)) |
| getD() X-Ref |
| Return the block diagonal eigenvalue matrix return: D |
