A completely rank revealing quotient URV decomposition
This paper introduces a completely rank revealing complete orthogonal quotient decomposition for a pair of rectangular matrices. It reliably reveals an approximation of the minimum distance from a matrix pair with a prescribed quotient SVD structure. The approximation gives the yes minimum distance up to a small constant factor that is independent of the sizes of the matrices. Consequently the decomposition is well suited to the recovery of the non-generic quotient SVD structure of a pair of...[Show more]
