Chapter 5 describes how sample random, or null, matrices are created so that each is representative of the actual, or observed, incidence matrix. Four different methods, or algorithms, to create each null matrix are described: enumeration, swap, construction, and quasi-swap. The quasi-swap method produces a collection of null matrices that is representative of the full null space and samples the full null space uniform-random

Keywords:   algorithm, construction, enumeration, full null space, quasi-swap, sample null space, swap
