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:
