julia 中的随机数
Random Number in julia
我想做一个1到30之间的随机数
我阅读了文档，但找不到执行此操作的方法
例如，我们在 php 中通过
进行
rand(1 , 30);
我该如何处理
文档中有解释https://docs.julialang.org/en/v1/stdlib/Random/#Base.rand
rand([rng=GLOBAL_RNG], [S], [dims...])
Pick a random element or array of random elements from the set of values specified by S; S can be
- an indexable collection (for example 1:9 or ('x', "y", :z)),
- an AbstractDict or AbstractSet object,
- a string (considered as a collection of characters), or
- a type: the set of values to pick from is then equivalent to typemin(S):typemax(S) for integers (this is not applicable to BigInt), to [0,1)[0, 1)[0,1) for floating point numbers and to [0,1)+i[0,1)[0, 1)+i[0, 1)[0,1)+i[0,1) for complex floating point numbers;
S defaults to Float64. When only one argument is passed besides the optional rng and is a Tuple, it is interpreted as a collection of values (S) and not as dims.
对于您的示例，它将是
rand(1:30)
您可以将范围传递给 rand 函数以生成两个其他数字之间的数字，包括：
julia> rand(1:30)
24
julia> rand(1:30)
18
