In mathematics, especially in linear algebra and matrix theory, a centrosymmetric matrix is a matrix which is symmetric about its center. == Formal definition == An n × n matrix A = [Ai, j] is centrosymmetric when its entries satisfy A i , j = A n − i + 1 , n − j + 1 for all i , j ∈ { 1 , … , n } .
