To convert a vector to a matrix in Julia, you can use the reshape function. This function takes a vector and a tuple of dimensions and returns a matrix with the specified dimensions. Below are the examples:
Convert vector to matrix in Julia Examples
julia> a = [1, 2, 3, 4, 5, 6]
6-element Array{Int64,1}:
1
2
3
4
5
6
julia> reshape(a, (2,3))
2x3 Array{Int64,2}:
1 3 5
2 4 6In this example, the vector a is converted to a 2x3 matrix. You can also use the hcat or vcat functions to convert a vector to a matrix by concatenating it with itself or another vector. Here are some examples:
julia> a = [1, 2, 3, 4, 5, 6]
6-element Array{Int64,1}:
1
2
3
4
5
6
julia> hcat(a, a)
2x6 Array{Int64,2}:
1 3 5 1 3 5
2 4 6 2 4 6
julia> vcat(a, a)
12-element Array{Int64,1}:
1
2
3
4
5
6
1
2
3
4
5
6In the first example, the vector a is concatenated horizontally with itself to create a 2x6 matrix. In the second example, a is concatenated vertically with itself to create a 12-element vector.
