Getting minimum elements in Julia – minimum() and minimum!() Methods

  • Last Updated : 07 Aug, 2021
Geek Week

The minimum() is an inbuilt function in julia which is used to return minimum elements in different scenario.

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. 
 

Example:  



Julia




# Julia program to illustrate
# the use of minimum() method
 
# Getting minimum elements in different scenarios
 
# In the below scenario, lenght function
# and a list of elements are used as
# parameter. Here the lenght 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))

Output: 

minimum!()

The minimum!() is an inbuilt function in julia which is used to calculate the minimum value of the specified array over the specified singleton dimensions.

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. 
 

Example:  

Julia




# 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))

Output: 

[5, 15]
[5 10]
