2021-02-22 2 PERMUTATION, MATRIX ℓ 1−2 PENALTY AND EXACT RELAXATION The channel shuffle operation in ShuffleNet [14, 23] can be repre-sented as multiplying the feature map in the channel dimension by a permutation matrix . The permutation matrix is a square binary matrix with exactly one entry of one in each row and each column and zeros elsewhere. Theorem: a permutation matrix is any matrix with a single one in each row and in each column. It is simply I with its rows (or columns) changed around. We can see that since there are n! orderings of the rows, there are n! permutation matrices of size n × n.

Every row and column therefore contains precisely a single 1 with 0s everywhere else, and every permutation corresponds to a unique permutation matrix. Sergio Pissanetzky, in Sparse Matrix Technology, 1984 2.6 Permutation matrices A permutation matrix P is a square matrix of order n such that each line (a line is either a row or a column) contains one element equal to 1, the remaining elements of the line being equal to 0. The simplest permutation matrix is I, the identity matrix. where PN+1 is a permutation matrix, when it is applied to a data vector it corresponds to the reordering (4.26) ˉx0 = x 0, ˉxn + 1 = x 2n + 2, ˉxN − n = x 2n + 1, n = 0, 1, …, N 2 − 1 The (N + 1)-point DCT-I is decomposed recursively into (N 2 + 1) -point DCT-I and N 2 -point DCT-III.

Such a matrix is always row equivalent to an identity. Every row and every column of a permutation matrix contain exactly one nonzero entry, which is 1: There are two 2 2 permutation matrices: [1 0 0 1]; [0 1 1 0]: 3 Permutation Matrices A permutation matrix is a square matrix that rearranges the rows of an other matrix by multiplication. A permutation matrix P has the rows of the identity I in any order.

Sometimes, we have to swap the rows of a matrix. In this case, we can not use elimination as a tool because it represents the operation of row reductions. permutation matrix.

A permutation matrix can also be returned from the built-in functions lu and qr, if a pivoted factorization is requested. The sparse function will convert a permutation matrix efficiently to a sparse matrix. The find function will also work efficiently with a permutation matrix, making it possible to conveniently obtain the permutation indices.
