WebbIf the matrix is invertible, then the inverse matrix is a symmetric matrix. The matrix inverse is equal to the inverse of a transpose matrix. If A and B be a symmetric matrix which is of equal size, then the summation (A+B) and subtraction (A-B) of the symmetric matrix is also a symmetric matrix.

(2) WebbSymmetry of a 5×5 matrix. In linear algebra, a symmetric matrix is a square matrix that is equal to its transpose. Formally, Because equal matrices have equal dimensions, only square matrices can be symmetric. The entries of a symmetric matrix are symmetric with respect to the main diagonal.

WebbAll main diagonal entries of a skew-symmetric matrix must be zero, so the trace is zero. If A = (a ij) is skew-symmetric, a ij = −a ji; hence a ii = 0. 3x3 skew symmetric matrices can be used to represent cross products as matrix multiplications.
