On matrix convexity of the Moore-Penrose inverse [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
Matrix convexity of the Moore-Penrose inverse was considered in the recent literature. Here we give some converse inequalities as well as further generalizations.

An efficient second‐order neural network model for computing the Moore–Penrose inverse of matrices

open access: yesIET Signal Processing, 2022
The computation of the Moore–Penrose inverse is widely encountered in science and engineering. Due to the parallel‐processing nature and strong‐learning ability, the neural network has become a promising approach to solving the Moore–Penrose inverse ...

Invers Moore-Penrose pada Matriks Turiyam Simbolik Real

open access: yesJambura Journal of Mathematics, 2023
The symbolic Turiyam matrix is a matrix whose entries contain symbolic Turiyam. Inverse matrices can generally be determined if the matrix is a non-singular square matrix. Currently the inverse of the symbolic Turiyam matrix of size m × n with m 6= n can

The Moore--Penrose Generalized Inverse for Sums of Matrices [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2000
Recall, that the Moore-Penrose generalized inverse of an \(m \times n\) matrix \(A\) is the unique matrix \(A^\perp\) satisfying \(AA^\perp A=A\), \(A^\perp AA^\perp=A^\perp\), \(AA^\perp\) and \(A^\perp A\) are Hermitian. In their main result (theorem 3) the authors find the formula for \((A+B)^\perp\) for \(n \times n\) matrices \(A\) and \(B\) in ...

On Nonnegative Moore-Penrose Inverses of Perturbed Matrices

open access: yesJournal of Applied Mathematics, 2013
Nonnegativity of the Moore-Penrose inverse of a perturbation of the form is considered when . Using a generalized version of the Sherman-Morrison-Woodbury formula, conditions for to be nonnegative are derived.

The Moore–Penrose inverse of a companion matrix

open access: yesLinear Algebra and Its Applications, 2012
Let \(R\) be a ring with identity and endowed with an involution. Let \({\mathcal M}_{m \times n} (R)\) denote the set of all matrices with \(m\) rows and \(n\) columns, with entries coming from \(R\). Let \(*\) be the involution on \({\mathcal M}_{m \times n} (R)\) induced by the involution on \(R\).

Weak dual generalized inverse of a dual matrix and its applications

open access: yesHeliyon, 2023
Recently, the dual Moore-Penrose generalized inverse has been applied to study the linear dual equation when the dual Moore-Penrose generalized inverse of the coefficient matrix of the linear dual equation exists.

A New Generalized Θ-Inverse vs. Moore-Penrose Structure: A Comparative Control-Oriented Practical Investigation

open access: yesIEEE Access, 2021
A new non-unique $\Theta $ -inverse of non-square polynomial matrices is presented in this paper. It is shown that the above inverse specializes to the unique Moore-Penrose one under several specific assumptions.

Existence of Moore-Penrose inverses in rings with involution [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2018
We give necessary and sufficient conditions for the existence of the Moore-Penrose inverse of an element in a ring with involution. If R is a ring with involution, we also investigate the existence of the Moore-Penrose inverse of the product 1 2 n x
