WebA matrix for which the transposed form is equal to the negative of the original matrix is called a skew-symmetric matrix. Any matrix can be expresses as a sum of a symmetric and a skew-symmetric matrix. For a square matrix A, A = (1/2)(A + A T) + (1/2)(A - A T). If the order of a skew-symmetric matrix is odd, then its determinant is equal to zero.
