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

Last Updated : 25 Apr, 2025

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, 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))

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]
