RandStream.list

List random number generator algorithms

Syntax

RandStream.list

RandStream.list lists all the generator algorithms that can be used when creating a random number stream with RandStream or RandStream.create.

The available generator algorithms and their properties are given in the following table.

Keyword	Generator	Multiple Stream and Substream Support	Approximate Period In Full Precision
mt19937ar	Mersenne twister (used by default stream at MATLAB^® startup)	No	2¹⁹⁹³⁷-1
dsfmt19937	SIMD-oriented fast Mersenne twister	No	2¹⁹⁹³⁷-1
mcg16807	Multiplicative congruential generator	No	2³¹-2
mlfg6331_64	Multiplicative lagged Fibonacci generator	Yes	2¹²⁴ (2⁵¹ streams of length 2⁷²)
mrg32k3a	Combined multiple recursive generator	Yes	2¹⁹¹ (2⁶³ streams of length 2¹²⁷)
philox4x32_10	Philox 4x32 generator with 10 rounds	Yes	2¹⁹³ (2⁶⁴ streams of length 2¹²⁹)
threefry4x64_20	Threefry 4x64 generator with 20 rounds	Yes	2⁵¹⁴ (2²⁵⁶ streams of length 2²⁵⁸)
shr3cong	Shift-register generator summed with linear congruential generator	No	2⁶⁴
swb2712	Modified subtract with borrow generator	No	2¹⁴⁹²
