Uniform Random Variables

get_std_uniform(shape=1; seed=nothing)

Generate a shape element array of random variables from a standard Uniform(0,1) distribution. Optionally you can set a specific seed.

Examples

julia> get_std_uniform()
1-element Vector{Float64}:
 0.42443098343863284

julia> get_std_uniform(seed=43)
1-element Vector{Float64}:
 0.09636209187468836

julia> get_std_uniform(5)
5-element Vector{Float64}:
 0.6584669595802204
 0.33437978955868886
 0.509019330923099
 0.12156905126458639
 0.917393216014684

uniform_rng(a, b, shape=1; seed=nothing)

Generate a shape element array of random variables from a Uniform(a, b) distribution. Optionally you can set a specific seed.

Notes

The Uniform distribution is given by:

$f(x, a, b) = \frac{1}{b-a} \quad \text{for} \quad a ≤ x ≤ b$

Examples

julia> uniform_rng(1, 6)
1-element Vector{Float64}:
 2.638331960912094

julia> uniform_rng(1, 6, seed=42)
1-element Vector{Float64}:
 2.6333962626438314

julia> uniform_rng(0, 1, (4,4))
4×4 Matrix{Float64}:

 0.955188   0.155203  0.953206  0.0046541
