Class BidiagonalDecompositionNaive_DDRM

java.lang.Object

org.ejml.dense.row.decomposition.bidiagonal.BidiagonalDecompositionNaive_DDRM

public class BidiagonalDecompositionNaive_DDRM
extends Object

A slower but much simpler version of BidiagonalDecompositionRow_DDRM that internally uses SimpleMatrix and explicitly computes the householder matrices. This was easier to code up and is used to validate other implementations.
