How to convert the augmented matrix A into four column vectors respectively

Hello i want asking about how i want to convert matrix into 4 column vector ?

here my homework question

1. convert the augmented matrix A into four column vectors respectively

should i put like this A2 = reshape(A.',4,[]) ?

My example matrix is

1. for Matrix A

M = [1 2 4; 0 6 1; 1 0 3]

M = 3×3

1 2 4 0 6 1 1 0 3

C=[1 1 1]'

C = 3×1

1 1 1

A = [M C],

A = 3×4

1 2 4 1 0 6 1 1 1 0 3 1

In your example, A already has 4 columns.

If you want to access a particular column, then you can simply assign them to variables as shown in the code below

>> A = [1 2 3 4; 5 6 7 8; 9 10 11 12]

>> C1 = A(:, 1)

>> C2 = A(:, 2)

If you want to access multiple columns or the matrix size is unknown, then you can separate columns using num2cell

>> A = [1 2 3 4; 5 6 7 8; 9 10 11 12]

>> C = num2cell(A, 1)

>> C{1}

>> C{2}

>> C{3}

>> C{4}

OR

[m n] = size(A);

for i = 1:n

C{i}

end
