Class BidiagonalDecompositionNaive_D64

java.lang.Object

org.ejml.alg.dense.decomposition.bidiagonal.BidiagonalDecompositionNaive_D64

public class BidiagonalDecompositionNaive_D64
extends java.lang.Object

A slower but much simpler version of BidiagonalDecompositionRow_D64 that internally uses SimpleMatrix and explicitly computes the householder matrices. This was easier to code up and is used to validate other implementations.
