¿La matriz es centrosimétrica ... y también lo es el código?
Definición A centrosymmetric matrix is a square matrix that is symmetric about its center. More rigorously, a matrix AAA of size n×nn×nn \times n is centrosymmetric if, for any i,j∈([1,n]∩Z)i,j∈([1,n]∩Z)i,\: j \in ([1, n] \cap \mathbb{Z}) the following relation is satisfied: Ai,j=An+1−i,n+1−jAi,j=An+1−i,n+1−jA_{i,\:j}=A_{n+1-i,\:n+1-j} Examples of such matrices Here is an illustration …
