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 with all other entries 0. 1 26 An n n permutation matrix can represent a permutation of n elements.Pre-multiplying an n-row matrix M by a permutation matrix P, forming PM, results in permuting the rows of M, while post-multiplying an n

De-nition 1 A permutation matrix is a matrix gotten from the identity by permuting the columns i.e., switching some of the columns. Now, the p p matrix L has rank less than p If it is less than or equal to p 2 then all determinants of p 1 p 1 submatrices are zero, and

The proof is by induction. A permutation matrix is obtained by performing a sequence of row and column interchanges on the identity matrix. We start from the identity matrix , we perform one interchange and obtain a matrix , we perform a second interchange and obtain another matrix , and so on until at the -th interchange we get the matrix .

Because the columns and rows of the identity matrix are orthonormal, the permutation matrix is an orthogonal matrix.

Permutation Matrices There is an n n permutation matrix P associated to an element p of the symmetric group Sn. This matrix acts on the entries of a vector as the permutation p. For example, the matrix associated to the cyclic permutation p 123 in S3 is 0 0 1 1 P 1 0 0 1 0 0 .

A permutation matrix is a matrix that, when multiplied with another matrix, leads to the interchange of columns or rows in the resulting matrix. That is, the rank of a matrix is equal to the maximum number of its columns which are linearly independent. For the example above, columns 1, 3 and 4 are linearly dependent

Proving that an algorithm can generate all permutations of a matrix 1 What is the rank of a normally distributed matrix that is multiplied by rank-r projection matrices from left and right.

3. If B is the canonical form of the permutation matrix A, how to nd the permutation matrix T, such that B T1AT? Theorem 1. Decomposition Theorem For any permutation matrix A of order n, if A is not identical, then there are some generalized cycle matrices Q1, Q2, , Q r of type II and a diagonal matrix D t of rank t, such that

Let Pb2Sn and P 2MnR be the permutation matrix of P. The minimum number ofb transpositions required to bring P to identity isb rankIn P. For example, if Pb2S 2 is the transposition 1 2, then P 0 1 1 0 . Clearly one transposition has to be applied to Pbto make it the identity, which must be the minimum. 1 is also the rank of In P 1 1 1 1 .
