Random number generator algorithms




RandStream.list lists all the generator algorithms that may 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.

KeywordGeneratorMultiple Stream and Substream SupportApproximate Period In Full Precision
mt19937arMersenne twister (used by default stream at MATLAB® startup)No
mcg16807Multiplicative congruential generatorNo
mlfg6331_64Multiplicative lagged Fibonacci generatorYes
mrg32k3aCombined multiple recursive generatorYes
shr3congShift-register generator summed with linear congruential generatorNo
swb2712Modified subtract with borrow generatorNo

See Choosing a Random Number Generator for details about these generator algorithms. See for a full description of the Mersenne twister algorithm.
