class SVD3 extends SVDecomp
The SVD3 class is used to solve Singular Value Decomposition for bidiagonal matrices.
The SVD3 class is used to solve Singular Value Decomposition for bidiagonal matrices.
It computes the singular values and, optionally, the right and/or left singular vectors from the singular value decomposition 'SVD' of a real n-by-n (upper) bidiagonal matrix B using the implicit zero-shift 'QR' algorithm. The 'SVD' of B has the form
B = Q * S * P.t
where S is the diagonal matrix of singular values, Q is an orthogonal matrix of left singular vectors, and P is an orthogonal matrix of right singular vectors. If left singular vectors are requested, this subroutine actually returns U*Q instead of Q, and, if right singular vectors are requested, this subroutine returns P.t * VT instead of P.T, for given real input matrices U and VT. When U and VT are the orthogonal matrices that reduce a general matrix A to bidiagonal form: A = U*B*VT, as computed by DGEBRD, then
A = (U*Q) * S * (P.t*VT)
is the 'SVD' of the general matrix A. A positive tolerance 'TOL' gives relative accuracy; for absolute accuracy negate it.

class SVD4 extends SVDecomp with Error
The SVD4 class is used to compute the Singular Value Decomposition 'SVD' of matrix 'aa' using the Golub-Kahan-Reinsch Algorithm.
The SVD4 class is used to compute the Singular Value Decomposition 'SVD' of matrix 'aa' using the Golub-Kahan-Reinsch Algorithm. Factor/decompose matrix 'aa' into the product of three matrices:
aa = uu * a * vv.t
where 'uu' is a matrix of orthogonal eigenvectors of 'aa * aa.t' (LEFT SINGULAR VECTORS) 'vv' is a matrix of orthogonal eigenvectors of 'aa.t * aa' (RIGHT SINGULAR VECTORS) and 'a' is a diagonal matrix of square roots of eigenvalues of 'aa.t * aa' & 'aa * aa.t' (SINGULAR VALUES). FIX: need to reorder so singular values are in decreasing order. FIX: make the singular values positive ------------------------------------------------------------------------------
class SVDImputed extends SVDecomp

The SVDImputed class is used to predict the missing values of an input matrix by employing the concept of column mean imputation and then applying Singular Value Decomposition to factor the matrix. Once the factors are obtained the missing value in the matrix is obtained as the dot product of 'p' and 'q', where
p = u * sqrt(s) left orthogonal matrix * Singular Values Vector q = sqrt(s) * v.t singular values vector * transpose of right orthogonal matrix predict (i, j) = p dot q
