WatchedDoubleStepQRDecomposition_DDRM (ejml-ddense 0.39 API)

java.lang.Object
- org.ejml.dense.row.decomposition.eig.WatchedDoubleStepQRDecomposition_DDRM

All Implemented Interfaces:

org.ejml.interfaces.decomposition.DecompositionInterface<org.ejml.data.DMatrixRMaj>, org.ejml.interfaces.decomposition.EigenDecomposition<org.ejml.data.DMatrixRMaj>, org.ejml.interfaces.decomposition.EigenDecomposition_F64<org.ejml.data.DMatrixRMaj>
```
public class WatchedDoubleStepQRDecomposition_DDRM
extends java.lang.Object
implements org.ejml.interfaces.decomposition.EigenDecomposition_F64<org.ejml.data.DMatrixRMaj>
```
Finds the eigenvalue decomposition of an arbitrary square matrix using the implicit double-step QR algorithm. Watched is included in its name because it is designed to print out internal debugging information. This class is still underdevelopment and has yet to be optimized.

Based off the description found in:
David S. Watkins, "Fundamentals of Matrix Computations." Second Edition.
