You could write a routine which does that for you:

my_array2 := new_array2 (3, 3, <<1, 2, 3, 4, 5, 6, 7, 8, 9>>)

new_array2 (a_width, a_height: INTEGER; a_values: ARRAY [INTEGER]): 
ARRAY2 [INTEGER]
    require
        a_width_not_negative: a_width >= 0
        a_height_not_negative: a_height >= 0
        a_values_not_void: a_values /= Void
        consistent_size: a_width * a_height = a_values.count
    do
        ...
