In particular, since permutation matrices are orthogonal matrices with nonnegative elements, we define two gradient flows in the space of orthogonal matrices. "A dynamical systems approach to weighted graph matching".
Most authors choose one representation to be consistent with other notation they have introduced, so there is generally no need to supply a name.
n-queens puzzle, a permutation matrix in which there is at most one entry in each diagonal and antidiagonal A permutation, also called an arrangement number or order, is a rearrangement of the elements of an ordered list S into a one-to-one correspondence with. Costas array, a permutation matrix in which the displacement vectors between the entries are all distinct. So, permutation matrices do indeed permute the order of elements in vectors multiplied with them. Each such matrix, say P, represents a permutation of m elements and, when used to multiply another matrix, say A, results in permuting the rows (when pre-multiplying, to form PA) or columns (when post-multiplying, to form AP) of the matrix A. In mathematics, particularly in matrix theory, a permutation matrix is a square binary matrix that has exactly one entry of 1 in each row and each column and 0s elsewhere. .jpg "permutation")
