Webdet A = det A T = det ( − A) = ( − 1) n det A. In particular, if n is odd, the determinant vanishes. The nonzero eigenvalues of a real skew-symmetric matrix are purely imaginary. Theorem: Every square matrix A can be expressed uniquely as the sum of two matrices S and V, where S = 1 2 ( A + A T) is symmetric and V = 1 2 ( A − A T) is skew ... WebIt says: write the permutation matrix which corresponds to the permutations listed in P. – Andrew Oct 24, 2011 at 19:32 As given here, P describes one permutation, namely the one that maps 1 to 2, 2 to 3, 3 to 1, 4 to 5 and 5 to 4. In cycle notation (if you're more familiar with that) it would be P = ( 1 2 3) ( 4 5). – hmakholm left over Monica
