Package org.ejml.dense.row.decomposition.eig

Class SwitchingEigenDecomposition_DDRM

java.lang.Object
org.ejml.dense.row.decomposition.eig.SwitchingEigenDecomposition_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 SwitchingEigenDecomposition_DDRM
extends java.lang.Object
implements org.ejml.interfaces.decomposition.EigenDecomposition_F64<org.ejml.data.DMatrixRMaj>
Checks to see what type of matrix is being decomposed and calls different eigenvalue decomposition algorithms depending on the results. This primarily checks to see if the matrix is symmetric or not.
