It is quite simple and straightforward:
G = tf(1, [1 4 3 0 1 3 0])

G = tf([1], [1, 4, 3, 3.553e-15, 1, 1, 0])
N = cellfun(@discardsmall, G.Numer, 'uniform', 0);
D = cellfun(@discardsmall, G.Denom, 'uniform', 0);
G = tf(N, D, 'IODelay', G.IODelay)
function V = discardsmall(V)
V(abs(V)<1e-10) = 0;
end
Using a function as a helper is the easiest way because for the general case we cannot assume that the input transfer function does not have an array of transfers. G.Numer and G.Denom are cell arrays of vectors, not plain vectors.
