嵌套追加到Julia中的数组 [英] Nested append to an Array in Julia

问题描述

在python中，它类似于:

In python this would be something like:

Z = []
z = 1
Z.append([z])

例如，将创建Z= [[1]]的

.但是在Julia中，我似乎无法重新创建相同的结构.我可以追加，但不知道如何嵌套.这是我正在做的总结:

which would create Z= [[1]] for example. But in Julia, I cannot seem to re-create the same structure. I can append, but don't know how to nest. Here is what I am doing in summary:

Z = []
# loop
z = dotProduct(X, yArray) # single digit
append!(Z, z)

然后生成以下内容

0Any[0, 0, 0, 0, 1, 1, 1, 1]

我想要的地方:

[[0], [0], [0], [0], [1], [1], [1], [1]]

在朱莉娅中做到这一点的最佳方法是什么?

What is the best way to do this in Julia?

推荐答案

我发现完成这项工作的唯一方法是:

The only way I found to make this work was the following:

Z = Array{Int64,1}[]
push!(Z, [1])
push!(Z, [2])
print(Z)

给予

Array{Int64,1}[[1], [2]]

不太优雅，但是如果没有Array关键字，我似乎无法正常工作.

Not very elegant, but I cannot seem to get this working without the Array keyword.
