MersenneTwister

MersenneTwister([seed])

Create a MersenneTwister RNG object. Different RNG objects can have their own seeds, which may be useful for generating different streams of random numbers.

Examples

1. Create a MersenneTwister RNG object with a default seed:

   julia> rng = MersenneTwister()
   MersenneTwister(123456789)

   This example creates a MersenneTwister random number generator object with the default seed value of 123456789.

2. Create a MersenneTwister RNG object with a specific seed:

   julia> rng = MersenneTwister(987654321)
   MersenneTwister(987654321)

   Here, a MersenneTwister RNG object is created with a seed value of 987654321.

3. Generate random numbers using the MersenneTwister RNG object:

   julia> rng = MersenneTwister(1234)
   MersenneTwister(1234)
   
   julia> rand(rng, 5)
   5-element Array{Float64,1}:
   0.590844
   0.766376
   0.566237
   0.256434
   0.672781

   In this example, the rand function is used with the MersenneTwister RNG object to generate an array of 5 random numbers.

Common mistake example:

julia> rng = MersenneTwister(-1)
ERROR: DomainError: The seed provided (-1) is outside the valid seed range for MersenneTwister.

Here, an invalid seed value of -1 is provided, which results in a DomainError since the seed must be within the valid range. Ensure that the seed value is a non-negative integer when using MersenneTwister.
