在 Julia 中获取最小元素 – minimum() 和 minimum!() 方法

minimum()是 julia 中的内置函数，用于返回不同场景中的最小元素。

Syntax: 
minimum(f, itr) 
or 
minimum(itr) 
or 
minimum(A::AbstractArray; dims)

Parameters: 

• f: Specified function.
• itr: Specified list of elements.
• A::AbstractArray: Specified array of different dimensions.
• dims: Specified dimensions.

Returns: It returns the minimum elements in different scenario. 
 

例子：

Julia

# Julia program to illustrate
# the use of minimum() method
 
# Getting minimum elements in different scenarios
 
# In the below scenario, length function
# and a list of elements are used as
# parameter. Here the length of string with
# minimum alphabets will be returned
println(minimum(length, ["GFG", "Geeks", "GeeksforGeeks"]))
 
# In the below scenario, a list of
# elements are shown and minimum elements are
# returned as output
println(minimum([5, 10, 15, 20]))
 
# Getting the minimum value of an array
# over the given dimensions
A = [5 10; 15 20];
println(minimum(A, dims = 1))
println(minimum(A, dims = 2))

输出：

minimum!()是 julia 中的内置函数，用于计算指定数组在指定单例维度上的最小值。

Syntax: minimum!(r, A)
Parameters: 

• r: Specified singleton dimensions.
• A: Specified array.

Returns: It returns the minimum value of the specified array over the specified singleton dimensions. 
 

例子：

朱莉娅

# Julia program to illustrate
# the use of minimum !() method
 
# Getting the minimum value of the
# specified array over the specified
# singleton dimensions.
A = [5 10; 15 20];
println(minimum !([1; 1], A))
println(minimum !([1 1], A))

输出：

[5, 15]
[5 10]
