All Known Implementing Classes:

BidiagonalDecomposition

public interface Bidiagonal<N extends Number>
extends MatrixDecomposition<N>

A general matrix [A] (m-by-n) can be factorized by similarity transformations into the form [A]=[Q1][D][Q2]^T where

• [D] (r-by-r) is (upper or lower) bidiagonal
• [Q1] (m-by-r) is orthogonal
• [Q2] (n-by-r) is orthogonal
• r = min(m,n)
