### Abstract

A truncated ULV decomposition (TULV) of an m×n matrix X of rank k is a decomposition of the form X = U_{1}LV ^{T} _{1} + E, where U_{1} and V1 are left orthogonal matrices, L is a k × k non-singular lower triangular matrix and E is an error matrix. Only U_{1}, V_{1}, L, and ∥E∥_{F} are stored. We propose algorithms for block updating the TULV based upon Block Classical Gram-Schmidt that in [4]. We also use a refinement algorithm that reduces ∥E∥_{F}, detects rank degeneracy, corrects it and sharpens the approximation.
