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.
