DefaultDeflationCriterion |
The default deflation criterion is to use eq.
|
Deflation |
A deflation found in a Hessenberg (or tridiagonal in symmetric case) matrix.
|
Hessenberg |
An upper Hessenberg matrix is a square matrix which has zero entries below the first
sub-diagonal.
|
HessenbergDecomposition |
Given a square matrix A, we find Q such that Q' * A * Q = H where
H is a Hessenberg matrix.
|
HessenbergDeflationSearch |
Given a Hessenberg matrix, this class searches the largest unreduced Hessenberg sub-matrix.
|
QRAlgorithm |
The QR algorithm is an eigenvalue algorithm by computing the real Schur canonical form of a
matrix.
|
SymmetricQRAlgorithm |
The symmetric QR algorithm is an eigenvalue algorithm by computing the real Schur canonical form
of a square, symmetric matrix.
|
TridiagonalDeflationSearch |
This class locates deflation in a tridiagonal matrix.
