use an array and write a function. E.g. 

type t_matrix is array (0 to 3) of bit_vector(0 to 3);
signal s_matrix : t_matrix := (others => (others => '0'));

function pivot_matrix(input_matrix : t_matrix) return t_matrix is
    variable output_matrix : t_matrix;
begin
    
    return output_matrix;
end function;
