WebSince the main diagonal elements are reflected into themselves, all of the main diagonal elements of a skew-symmetric matrix must be zeroes ( aii = − aii only if aii = 0). Notice that any diagonal matrix is equal to its transpose, and so such matrices are automatically symmetric. Another useful result is the following: Theorem 1.14 WebSince the main diagonal elements are reflected into themselves, all of the main diagonal elements of a skew-symmetric matrix must be zeroes ( aii = − aii only if aii = 0).
