A1X = C1, A1X = C1, XB3 = C3, A2X = 62, to have bisymmetric solutions, and the system A1X = Ca, A3X B3 = C3, to have centrosymmetric solutions. The expressions of such solutions of the matrix and the systems mentioned above are also given. Moreover a criterion for a quaternion matrix to be bisymmetric is established and some auxiliary results on other sets over H are also mentioned. ~) 2005 Els...

Mechanoluminescent (ML) materials featuring renewable mechanical-to-optical conversion have shown promising prospects in stress sensing, lighting, and display. However, the advancement ML applications is being restrained by obstacles developing efficient understanding underlying mechanisms. Herein, a matrix evolution strategy to modulate local microstructure electronic environment around lumine...

A matrix is a collection of numbers that are often also called regularly arranged entries by rows and colums. There several types matrices, such as Centrosymmetric matrix. The concept very useful in solving some problems mathematics. One the most common mathematics system linear equations. way to determining inverse using Adjoin Method. This study aims determine special shape Method

By using Moore-Penrose generalized inverse and the general singular value decomposition of matrices, this paper establishes the necessary and sufficient conditions for the existence of and the expressions for the centrosymmetric solutions with a submatrix constraint of matrix inverse problem AX = B. In addition, in the solution set of corresponding problem, the expression of the optimal approxi...
