WebFeb 12, 2024 · Properties and Examples. Skew symmetric matrix is a square matrix Q= [x ij] in which (i, j) th element is negative of the (j, i) th element i.e. x ij = -x ji for all values of i and j. In other words, a square matrix (Q) which is equal to negative of its transpose is known as skew-symmetric matrix i.e. Q T = -Q. WebDec 24, 2024 · Since every square of a skew-symmetric matrix is symmetric, and the symmetric and the skew-symmetric matrices are orthogonal, we know that every skew-symmetric matrix belongs to the dual cone of C. So, the question whether a given matrix A belongs to the dual cone of C depends solely on the symmetric part of A.
