Takagi's factorization

WebA complex symmetric matrix A can always be factored as A = UΣU T, in which U is complex unitary and Σ is a real diagonal matrix whose diagonal entries are the singular values of A.This factorization may be thought of as a special singular value decomposition for complex symmetric matrices. We present an analogous special singular value … Websf.decompositions.takagi. ¶. takagi(N, tol=1e-13, rounding=13) [source] ¶. Autonne-Takagi decomposition of a complex symmetric (not Hermitian!) matrix. Note that singular values of N are considered equal if they are equal after np.round (values, tol). See [25] and references therein for a derivation.

WebFor any matrix A, there exists a singular value decomposition (SVD). One method of computing the SVD involves a generalization of the method used to compute the Takagi factorization for square symmetric matrices. The Takagi factorization is: where Q is unitary and is the diagonal singular value matrix.
