在 Julia 中表示数组的维度 – Dims() 方法
Dims()
是 julia 中的内置函数,用于表示指定 AbstractArray 的维度。
Syntax: Dims(A)
Parameters:
- A: Specified array
Returns: It returns the represented dimensions of the specified AbstractArray.
示例 1:
# Julia program to illustrate
# the use of Dims() method
# Getting the represented dimensions
# of the specified AbstractArray.
A = [1, 2, 3, 4]
println(Dims(A))
B = (5, 10, 15, 20)
println(Dims(B))
输出:
(1, 2, 3, 4)
(5, 10, 15, 20)
示例 2:
# Julia program to illustrate
# the use of Dims() method
# Getting the represented dimensions
# of the specified AbstractArray.
A = [1 2 3; 4 5 6]
println(Dims(A))
B = cat([1 2; 3 4], [5 6; 7 8], [2 2; 3 4], dims = 3)
println(Dims(B))
输出:
