Getting exclusive elements of a set in Julia - setdiff() and setdiff!() Methods

Set elements at a given index of array in Julia - setindex!() Method

Last Updated : 25 Apr, 2025

The setindex!() is an inbuilt function in julia which is used to store values from the given array X within some subset of A as specified by inds.

Syntax:

setindex!(A, X, inds...)

Parameters:

A: Specified function.
X: Specified array.
inds: Specified index.

Returns: It does not return any values.

Example 1:

Python

# Julia program to illustrate 
# the use of Array setindex!() method

# This function store values from an array
# X within some subset of A as 
# specified by inds.
A = zeros(2, 2);
setindex !(A, [5, 10], [1, 2]);
A[[3, 4]] = [15, 20];
println(A)

Output:

Example 2:

Python

# Julia program to illustrate 
# the use of Array setindex!() method

# This function store values from an array
# X within some subset of A as 
# specified by inds.
A = ones(2, 2);
setindex !(A, [2, 4], [1, 2]);
A[[3, 4]] = [6, 8];
println(A)
