Websymmetric matrices like with numbers: for example, we can solve B2 = A for B if A is symmetric matrix and B is square root of A.) This is not possible in general. There is no matrix B for example such that B2 = " 0 1 0 0 #. Recall the following deﬁnition: A real matrix is called symmetricif AT = A. Symmetric matrices are also called selfadjoint. WebApr 6, 2024 · If the elements on the main diagonal are the inverse of the corresponding element on the main diagonal of the D, then D is a diagonal matrix. If the transpose of a matrix is equal to itself, that matrix is said to be symmetric. Therefore, the inverse of a diagonal matrix is a Symmetric and Diagonal matrix.
