mathematics, a bisymmetric matrix is a square matrix that is symmetric about both of its main diagonals. More precisely, an n × n matrix A is bisymmetric if it...

matrices used in mathematics, science and engineering. A matrix (plural matrices, or less commonly matrixes) is a rectangular array of numbers called entries...

JA are called bisymmetric matrices. Bisymmetric matrices are both centrosymmetric and persymmetric. Pauli matrices (the first Pauli matrix is a 2 × 2 exchange...

that commute with a fixed matrix A has also been studied. Symmetric centrosymmetric matrices are sometimes called bisymmetric matrices. When the ground...

In linear algebra, a Toeplitz matrix or diagonal-constant matrix, named after Otto Toeplitz, is a matrix in which each descending diagonal from left to...

circulant matrices belong to the class of bisymmetric matrices. The complex version of the circulant matrix, ubiquitous in communications theory, is usually...

rotated by 90°, it becomes a persymmetric matrix. Symmetric persymmetric matrices are sometimes called bisymmetric matrices. The second definition is due...
