| Hessenberg.DeflationCriterion |
Deflation of an upper Hessenberg matrix splits it into multiple smaller upper Hessenberg matrices
when the sub-diagonal entries are sufficiently small.
|
| Class | Description |
|---|---|
| Hessenberg |
An upper Hessenberg matrix is a square matrix which has zero entries below the first sub-diagonal.
|
| Hessenberg.DefaultDeflationCriterion |
The default deflation criterion is to use eq.
|
| Hessenberg.Deflation |
This class encapsulates the indices for the upper left hand corner and lower right hand corner of H22 as a result of the deflation procedure.
|
| HessenbergDecomposition |
Given a square matrix A, we find Q such that Q' * A * Q = H where H is a Hessenberg matrix.
|
| QRAlgorithm |
The QR algorithm is an eigenvalue algorithm by computing the real Schur canonical form of a matrix.
