sort(x) = [0, 1/3, 4]``

NULL

f_x_MTM := [seq(convert([x[n], n], float), n = 1 .. 3)] = [[.3333333333, 1.], [0., 2.], [4., 3.]]NULL

sort(f_x_MTM) = [[.3333333333, 1.], [0., 2.], [4., 3.]]NULL

NULL

unwith(MTM):

f_x := [seq(convert([x[n], n], float), n = 1 .. 3)] = [[.3333333333, 1.], [0., 2.], [4., 3.]]

NULL

sort(f_x) = [[0., 2.], [.3333333333, 1.], [4., 3.]]
