NUMSTREAMS must be a positive integer value less than 2^64. SEED must be a nonnegative integer value less than 2^32. STREAMINDICES must contain positive integer values less than or equal to NUMSTREAMS. PARAMETERS must be a vector of non-negative integer values. PARAMETERS is not allowed for {0} generators. Too many output arguments. GENTYPE must be a character vector containing the name of a generator algorithm. Unknown RNG type: {0}. Error creating stream.
