Web2 feb. 2024 · If matrix B is symmetric then B^n[/latex] is also symmetric, where n is an integer. If the inverse of a symmetric matrix i.e \(B^{^{-1}}\) exists then it will be symmetric only if B is a symmetric matrix. \(A A^T\) is always a symmetric matrix. A scalar multiple of a symmetric matrix also results in a symmetric matrix. WebScalar matrix: A diagonal matrix having all the diagonal elements equal to each other. Example: . 7.

They contain three properties, including: Real eigenvalues, eigenvectors corresponding to the eigenvalues that are orthogonal and the matrix must be diagonalizable. A trivial example is the identity matrix. A non-trivial example can be something like:
WebA symmetric matrix has the property that elements above and below the main diagonal are the same such that element(i,j) = element(j,i), as in our matrix B. (The main or principal diagonal in matrix Bis composed of elements all equal to 1.) With a square, symmetric matrix, the transpose of the matrix is the original matrix.
