WebN2 - In this paper, several existing results related to secondary transpose are critically reviewed and a result analogous to spectral decomposition theorem is obtained for a real secondary symmetric matrix. Noting that Moore-Penrose inverse with reference to secondary transpose involution, namely s-g inverse, need not always exist, we explore ... WebOct 31, 2024 · Therefore, you could simply replace the inverse of the orthogonal matrix to a transposed orthogonal matrix. Positive Definite Matrix If the matrix is 1) symmetric, 2) all …
WebMay 10, 2012 · For example, assume that you would like to find the product of your inverse times a vector v, i.e. w := (X^T X)^ {-1} v. In this case, you are actually looking for a solution to the problem Find w such that (X^T X) w = v Using iterative algorithms, it is possible to find w given X and v in the equation above without inverting X. WebIf Ais an invertible symmetric matrix then A-1is also symmetric. The product of symmetric matrices does not need to be symmetric. Example. Let A= B= then AB= Both Aand Bare symmetric but ABis not symmetric. In fact the following result holds. Theorem. If the product of two symmetric matrices Aand Bof the same size is symmetric then AB=BA.
