A note on the Moore-Penrose inverse of block matrices
نویسندگان
چکیده
Motivated by the representation for Moore-Penrose inverse of block matrix over a *-regular ring presented in [R.E. Hartwig and P. Patr?cio, When does flip? Operators Matrices, 6(1):181-192, 2012], we show that formula is same as expression given [Nieves Castro-Gonz?lez, Jianlong Chen Long Wang, Further results on generalized inverses rings with involution, Elect. J. Linear Algebra, 30:118-134, 2015].

Fast Computation of Moore-Penrose Inverse Matrices
Many neural learning algorithms require to solve large least square systems in order to obtain synaptic weights. Moore-Penrose inverse matrices allow for solving such systems, even with rank deficiency, and they provide minimum-norm vectors of synaptic weights, which contribute to the regularization of the input-output mapping. It is thus of interest to develop fast and accurate algorithms for ...
متن کاملThe Moore-Penrose Generalized Inverse for Sums of Matrices
In this paper we exhibit, under suitable conditions, a neat relationship between the Moore–Penrose generalized inverse of a sum of two matrices and the Moore–Penrose generalized inverses of the individual terms. We include an application to the parallel sum of matrices. AMS 1991 subject classifications. Primary 15A09; secondary 15A18.
متن کاملThe Moore-Penrose Inverse of Intuitionistic Fuzzy Matrices
In this paper, we define the various g-inverses of an intuitionistic fuzzy matrices, left (right ) cancelable intuitionistic fuzzy matrices and derive the equivalent condition for the existence of the generalized inverses . We also study the relation between the minus-ordering and the various g–inverses of an intuitionistic fuzzy matrix.
متن کاملMinors of the Moore - Penrose Inverse ∗
Let Qk,n = {α = (α1, · · · , αk) : 1 ≤ α1 < · · · < αk ≤ n} denote the strictly increasing sequences of k elements from 1, . . . , n. For α, β ∈ Qk,n we denote by A[α, β] the submatrix of A with rows indexed by α, columns by β. The submatrix obtained by deleting the α-rows and β-columns is denoted by A[α′, β′]. For nonsingular A ∈ IRn×n, the Jacobi identity relates the minors of the inverse A−1...
متن کاملWhen Does the Moore–penrose Inverse Flip?
In this paper, we give necessary and sufficient conditions for the matrix [ a 0 b d ] , over a *-regular ring, to have a Moore-Penrose inverse of four different types, corresponding to the four cases where the zero element can stand. In particular, we study the case where the MoorePenrose inverse of the matrix flips. Mathematics subject classification (2010): 15A09, 16E50, 16W10.
