Numerical Range of Moore–Penrose Inverse Matrices [PDF]

open access: yesMathematics, 2020
Let A be an n-by-n matrix. The numerical range of A is defined as W ( A ) = { x * A x : x ∈ C n , x * x = 1 } . The Moore–Penrose inverse A + of A is the unique matrix satisfying A A + A = A , A + A A + = A ...

Reverse order law for outer inverses and Moore-Penrose inverse in the context of star order [version 1; peer review: 2 approved] [PDF]

open access: yesF1000Research, 2022
The reverse order law for outer inverses and the Moore-Penrose inverse is discussed in the context of associative rings. A class of pairs of outer inverses that satisfy reverse order law is determined.

A Neural Network for Moore–Penrose Inverse of Time-Varying Complex-Valued Matrices

open access: yesInternational Journal of Computational Intelligence Systems, 2020
The Moore–Penrose inverse of a matrix plays a very important role in practical applications. In general, it is not easy to immediately solve the Moore–Penrose inverse of a matrix, especially for solving the Moore–Penrose inverse of a complex-valued ...

Invers Moore-Penrose pada Matriks Turiyam Simbolik Real [PDF]

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

On optimisation of Paganin's method for propagation‐based X‐ray phase‐contrast imaging and tomography [PDF]

open access: yesJournal of Microscopy, Volume 303, Issue 1, Page 37-52, July 2026.
Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...

A genuine extension of the Moore-Penrose inverse to dual matrices [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2023
The Moore-Penrose inverse is a genuine extension of the matrix inverse. Given a complex matrix, there uniquely exists another complex matrix satisfying the four Moore-Penrose conditions, and if the original matrix is nonsingular, it is exactly the ...
