broadcast!_function

broadcast!_function(f)

Like broadcast_function, but for broadcast!.

Examples

In the Julia programming language, the function broadcast!(f, args...)

Modify the given args in-place by applying the function f to each corresponding element of the arguments.

jldoctest
julia> arr = [1, 2, 3, 4, 5];
julia> broadcast!((x) -> x^2, arr)
5-element Array{Int64,1}:
  1
  4
  9
 16
 25

Provide common examples of its use. If there are any common mistakes users make, add an example.

Square each element in an array:
```
julia> arr = [1, 2, 3, 4, 5];
julia> broadcast!((x) -> x^2, arr)
5-element Array{Int64,1}:
1
4
9
16
25
```
This example applies the square function to each element of the array arr in-place.

Element-wise addition of two arrays:

julia> arr1 = [1, 2, 3, 4, 5];
julia> arr2 = [10, 20, 30, 40, 50];
julia> broadcast!(+, arr1, arr2)
5-element Array{Int64,1}:
11
22
33
44
55

It performs element-wise addition between arr1 and arr2 in-place.

Increment each element by a constant:

julia> arr = [1, 2, 3, 4, 5];
julia> broadcast!((x) -> x + 10, arr)
5-element Array{Int64,1}:
11
12
13
14
15

This example increments each element of the array arr by 10 in-place.

Common mistake example:

julia> arr1 = [1, 2, 3];
julia> arr2 = [10, 20, 30, 40];
julia> broadcast!(+, arr1, arr2)
ERROR: DimensionMismatch: arrays could not be broadcast to a common size

In this example, the arrays arr1 and arr2 have different sizes. It's important to ensure that the dimensions of the arrays being operated on are compatible to avoid such errors when using broadcast!.
