Class BidiagonalDecompositionNaive

java.lang.Object
  org.ejml.alg.dense.decomposition.bidiagonal.BidiagonalDecompositionNaive

public class BidiagonalDecompositionNaive
extends Object

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