![]() ![]() Similarly, each diagonal element of a skew-symmetric matrix must be zero, since each is its own negative. The following 3×3 matrix is symmetric:Įvery diagonal matrix is symmetric, since all off-diagonal entries are zero. So if the entries are written as A = ( a ij), thenįor all indices i and j. The entries of a symmetric matrix are symmetric with respect to the main diagonal (top left to bottom right). In linear algebra, a symmetric matrix is a square matrix that is equal to its transpose.
