Parallel computing methods to determine parametric generalized inverse matrices

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevancy of the work is conditioned by the necessity to determine effectively the Moore-Penrose generalized parametric inverse matrices which are quite often encountered when solving non-autonomous linear systems of finite equations, optimal control

On the mean and dispersion of the Moore-Penrose generalized inverse of a Wishart matrix [PDF]

open access: yes, 2019
The Moore-Penrose inverse of a singular Wishart matrix is studied. When the scale matrix equals the identity matrix the mean and dispersion matrices of the Moore-Penrose inverse are known. When the scale matrix has an arbitrary structure no exact results

Approximating the Inverse of a Square Matrix with Application in Computation of the Moore-Penrose Inverse

open access: yesJournal of Applied Mathematics, 2014
This paper presents a computational iterative method to find approximate inverses for the inverse of matrices. Analysis of convergence reveals that the method reaches ninth-order convergence.

Minors of the Moore-Penrose inverse

open access: yesLinear Algebra and its Applications, 1993
The well-known Jacobi identity for the minors of an inverse matrix \(A^{-1}\) is generalized to the minors of the Moore-Penrose inverse \(A^ +\) of an arbitrary real \(m \times n\)-matrix \(A\) of rank \(r \geq 1\). As a consequence, conditions are given in the case \(m=n\), under which all principal minors of \(A^ +\) are nonnegative.

On the Further Properties of the MPBT Inverse and Applications to Special Matrices

open access: yesMathematics
This paper aims to simplify the form of the MPBT inverse, further explore its properties, and discuss when it coincides with other generalized inverses. Notably, the MPBT inverse coincides with the Moore–Penrose inverse when the index of the matrix is at
