Getting maximum elements in Julia – maximum() and maximum!() Methods
The maximum() is an inbuilt function in julia which is used to return maximum elements in different scenario.
Syntax:
maximum(f, itr)
or
maximum(itr)
or
maximum(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 maximum elements in different scenario.
Example:
Julia
# Julia program to illustrate # the use of maximum() method # Getting maximum 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 # maximum alphabets will be returned println(maximum(length, [ "GFG" , "Beginner" , "w3wiki" ])) # In the below scenario, a list of # elements are shown and maximum elements are # returned as output println(maximum([ 5 , 10 , 15 , 20 ])) # Getting the maximum value of an array # over the given dimensions A = [ 5 10 ; 15 20 ]; println(maximum(A, dims = 1 )) println(maximum(A, dims = 2 )) |
Output:
The maximum!() is an inbuilt function in julia which is used to calculate the maximum value of the specified array over the specified singleton dimensions.
Syntax: maximum!(r, A)
Parameters:
- r: Specified singleton dimensions.
- A: Specified array.
Returns: It returns the maximum value of the specified array over the specified singleton dimensions.
Example:
Julia
# Julia program to illustrate # the use of maximum !() method # Getting the maximum value of the # specified array over the specified # singleton dimensions. A = [ 5 10 ; 15 20 ]; println(maximum !([ 1 ; 1 ], A)) println(maximum !([ 1 1 ], A)) |
Output:
[10, 20] [15 20]
