RNGStreams: Parallel RNG Streams

In kuwisdelu/matter: Scientific computing for out-of-memory signals and images

Parallel RNG Streams

Description

These functions provide utilities for working with multiple streams of pseudo-random numbers.

Usage

RNGStreams(n = length(size), size = 1L)

getRNGStream()

setRNGStream(seed = NULL, kind = NULL)

Arguments

n	The number of RNG streams to create.
size	If RNGkind is set to "L'Ecuyer-CMRG", then iterate this number of RNG substreams between each returned stream.
seed	A valid RNG stream to assign to .Random.seed, or a list with elements named seed and kind.
kind	The RNGkind to use when setting the RNG stream.

Value

For RNGStreams, a list of length n with RNG streams (with elements named seed and kind) for use with setRNGStream.
