In Julia, the vectorized dot operator is used to apply a binary operation on each element of the array or vector. It is useful when we want to apply a particular binary operation on the entire array of elements. For example, if want to multiply each element in the array with number 5, we can use the vectorized dot operator as follows.
Input: [1, 2, 3, 4] .* 5
Output: [5, 10, 15, 20]
array . binary_operation
Let us take a look at an example of this.
#given arrayarr = [1, 2, 3, 4]# usage of vectorized dot operatorprintln(arr .* 5)
In the above code snippet,
Line 2: We declare and initialize an array of numbers and assign it to variable, arr.
Line 5: We multiply each element in the array arr with 5 using the vectorized dot operator.
