To load a vector into a single column of an array in Julia, you can use the following code snippet:
# Create a vector
vector = [1, 2, 3, 4, 5]
# Create an array with a single column
array = zeros(Int, length(vector), 1)
# Load the vector into the array
array[:, 1] = vector
In this code, we first create a vector with some values. Then, we create an array with the desired dimensions, where the second dimension has a size of 1 to represent a single column.
