Abstract: Given a matrix A with numerical rank k, the two-sided orthogonal decomposition (TSOD) computes a factorization A = UDV T, where U and V are orthogonal, and D is (upper/lower) triangular.

A translation of Tim Davis's Concise LDLᵀ Factorization, part of SuiteSparse with several improvements. This package is appropriate for matrices A that possess a factorization of the form LDLᵀ without ...
