On generalized inverses of singular matrix pencils
- International Journal of Applied Mathematics and Computer Science
, 2011
"... Linear time-invariant networks are modelled by linear differential-algebraic equations with constant coefficients. These equations can be represented by a matrix pencil. Many publications on this subject are restricted to regular matrix pencils. In particular, the influence of the Weierstrass struct ..."

structure of a regular pencil on the poles of its inverse is well known. In this paper we investigate singular matrix pencils. The relations between the Kronecker structure of a singular matrix pencil and the multiplicity of poles at zero of the Moore–Penrose inverse and the Drazin inverse of the rational
A Singular Value Thresholding Algorithm for Matrix Completion
, 2008
"... This paper introduces a novel algorithm to approximate the matrix with minimum nuclear norm among all matrices obeying a set of convex constraints. This problem may be understood as the convex relaxation of a rank minimization problem, and arises in many important applications as in the task of reco ..."

-to-implement algorithm that is extremely efficient at addressing problems in which the optimal solution has low rank. The algorithm is iterative and produces a sequence of matrices {X k, Y k} and at each step, mainly performs a soft-thresholding operation on the singular values of the matrix Y k. There are two
Reduction Theorem on Singular Matrix with Special Properties
"... This paper presents how a singular matrix of order n×n formulated using special properties to its immediate low order n-1×n-1 and we have also found that any square matrix taken randomly from an n×n special properties ’ singular matrix is also singular. This work shows the results of various operati ..."

Orbit Closures of Singular Matrix Pencils
- J. Pure Appl. Algebra
, 1992
"... Equivalence of matrix pencils (pairs of p\Thetaq matrices over C ) is given by the GL p \ThetaGL q -action of simultaneous left and right multiplication. The orbits under this group action were described by Kronecker in 1890 in terms of pencil invariants: column indices, row indices, and elementary ..."

A multilinear singular value decomposition
- SIAM J. Matrix Anal. Appl
, 2000
"... Abstract. We discuss a multilinear generalization of the singular value decomposition. There is a strong analogy between several properties of the matrix and the higher-order tensor decomposition; uniqueness, link with the matrix eigenvalue decomposition, first-order perturbation effects, etc., are ..."

Linearizations of singular matrix polynomials and the recovery of minimal indices
, 2009
"... A standard way of dealing with a regular matrix polynomial P(λ) is to convert it into an equivalent matrix pencil – a process known as linearization. Two vector spaces of pencils L1(P) and L2(P) that generalize the first and second companion forms have recently been introduced by Mackey, Mackey, M ..."

, Mehl and Mehrmann. Almost all of these pencils are linearizations for P (λ) when P is regular. The goal of this work is to show that most of the pencils in L1(P)andL2(P)arestill linearizations when P (λ) is a singular square matrix polynomial, and that these linearizations can be used to obtain
Stochastic Perturbation Theory
, 1988
"... . In this paper classical matrix perturbation theory is approached from a probabilistic point of view. The perturbed quantity is approximated by a first-order perturbation expansion, in which the perturbation is assumed to be random. This permits the computation of statistics estimating the variatio ..."
