WebDec 5, 2024 · In this video we will talk about determinant of a skew symmetric matrix of odd order.We will prove that : If A is a square matrix of order n such that A is s... WebIn 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. So if denotes the entry in the th row and th column then.
