Julia:在二维数组中转换数组数组 [英] Julia: Transforming an Array of Arrays in a 2-dimensional Array

问题描述

我有一个数组 d，其中包含一个浮点数组:

I have an Array d that contains an Array of floats:

julia> d
99-element Array{Array{Float64,1},1}:
...

我正在尝试将其转换为二维数组，并成功实现了我的目标:

I'm trying to convert it into a 2-dimensional Array, and I sucessfully achieved my goal with:

data = Array(Float64,length(d),length(d[1]))
for i in 1:length(d)
    for j in 1:length(d[1])
        data[i,j] = d[i][j]
    end
end

有没有更简单的方法?

推荐答案

hcat(d...) 和 vcat(d...) 应该做你想做的事想.

hcat(d...) and vcat(d...) should do what you want.
