    abstract     = "This thesis investigates the possibility of a sparse symmetric rank-revealing {VSV} decomposition. Rank-revealing decompositions of both general and symmetric rank-deficient matrices are described, as well as the numerical tools used in these. The cause of fill in the {VSV} decomposition is investigated, and numerical experiments with possible sparsity optimizations are discussed. Drop-tolerances in the estimated singular vectors are described as a tool in obtaining a sparse decomposition."
