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 ). WebSOBOL generates the stream and initializes it, specifying the array params [] of n 32-bit integers to set the dimension dimen of a quasi-random vector as well as pass other generator related parameters. For example, initial direction numbers and primitive polynomials. Direction numbers can also be passed using the array.
