For a copy of this paper, either


The ULV/ULLV Toolbox consists of a number of Matlab routines for calculation of Rank-Revealing ULV/ULLV Decompositions. This includes initial calculation of the decompositions and up/downdating methods. The algorithms are based on Givens rotations, i.e., for-loops, resulting in a slow execution of Matlab m-files. Therefore, a c-version is also available with a mex-file interface. Totally, the package consist of 31 m-files and 53 c-files, and the present reference documentation covers the m-version.
