arrays - 如何在Julia中将一维数组转换为元组？(How to convert a 1D array to tuple in Julia?)

Question

I want to reshape an array in Julia using the reshape function but the shape of the new array is stored as a 1-D array itself.

(我想使用reshape函数在Julia中对数组进行整形，但是新数组的形状本身存储为一维数组。)

reshape takes tuples as argument but not 1D array.

(reshape将元组作为参数，而不是一维数组。)

For example, I want to be able to do this:

(例如，我希望能够做到这一点：)

reshape([1 2 3 ; 4 5 6],(3,2))

but using [3,2] instead of (3,2) as the input to the shape parameter.

(但使用[3,2]代替(3,2)作为shape参数的输入。)

Converting array [3,2] to tuple (3,2) seems like the obvious thing to do, but if that can't be done, maybe I need to write another reshape function?

(将数组[3,2]转换为元组(3,2)似乎是显而易见的事情，但是如果无法完成，也许我需要编写另一个reshape函数？)

Any advice is appreciated.

Answer 1

You can splat the array:

(您可以图示数组：)

julia> reshape([1 2 3 ; 4 5 6], [3,2]...)
3×2 Array{Int64,2}:
 1  5
 4  3
 2  6
