Reshaping array as a vector in Julia - vec() Method Last Updated : 12 Jul, 2025 Comments Improve Suggest changes Like Article Like Report The vec() is an inbuilt function in julia which is used to reshape the specified array as a one-dimensional column vector i.e, 1D array. Syntax: vec(a::AbstractArray) Parameters: a::AbstractArray: Specified array. Returns: It returns the reshaped 1D array. Example 1: Python # Julia program to illustrate # the use of Array vec() method # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. A = ["a", "b", "c", "d"]; println(vec(A)) # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. B = ["ab" "bc"; "cd" "df"]; println(vec(B)) # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. C = cat(["a" "b"; "c" "d"], ["e" "f"; "g" "h"], ["i" "j"; "k" "l"], dims = 3); println(vec(C)) Output: Example 2: Python # Julia program to illustrate # the use of Array vec() method # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. A = [1, 2, 3, 4]; println(vec(A)) # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. B = [1 2; 3 4]; println(vec(B)) # Reshaping the specified array as a # one-dimensional column vector # i.e, 1D array. C = cat([1 2; 3 4], [5 6; 7 8], [9 10; 11 12], dims = 3); println(vec(C)) Output: Comment More infoAdvertise with us Next Article Reshaping array dimensions in Julia | Array reshape() Method K Kanchan_Ray Follow Improve Article Tags : Julia Julia Array-functions Similar Reads Creation of vectors in Julia - vect() Method The vect() is an inbuilt function in julia which is used to create a vector with the passed elements as parameter.

We are familiar with the data frame objects and packages in python, which includes pandas, matplotlib so on, and so forth. Exactly with the equivalent approach in Julia, we use pandas.jl which operates as an 5 min read Fill an array with specific values in Julia | Array fill() method The fill() is an inbuilt function in julia which is used to return an array of specified dimensions filled with a specific value passed to it as parameter. Syntax: fill(Value, Dimension)Parameters:  Value: To be filled in the arrayDimension: Required size of the array Returns: It returns an array 2 min read Reverse array elements in Julia - reverse(), reverse!() and reverseind() Methods The reverse() is an inbuilt function in julia which is used to reverse the specified vector v from start to stop.
