WebDec 30, 2011 · Note that DirectionNumbers returns the (integer) numerators of the direction number sequence, which is the form in which they will be used for generating the Sobol sequence. If no direction numbers are specified, the function assumes all initial values are one ( unit initialization ). WebThe two-argument interface provides a convenient way to obtain multiple random numbers at once. Even more importantly, there is a significant efficiency advantage to generating a large number of pseudorandom numbers at once.

There is some freedom in the selection of initial direction numbers. Therefore, it is possible to receive different realisations of the Sobol’ sequence for selected dimensions. A bad selection of initial numbers can considerably reduce the efficiency of Sobol’ sequences when used for computation.
