Web21 de out. de 2011 · That is a different matter than constructing matrices whose entries have a uniform distribution within a given range and the matrix as a whole is PD. Such matrices appear to be relatively rare to start with; to require uniform random distribution on the entries appears to make them difficult to generate. Web1 de mai. de 2015 · The probability that C = 0 is at least P ( A = 0) + P ( B = 0), which is greater than the probability that a uniform C is zero. A sufficient condition for uniformity, however, is that A be uniform among the surjective matrices - namely, for each C, the set A − 1 ( C) has the same cardinality and therefore the same probability.
