• Special Case 1: If an entire row in the Routh array is zero,
• Special Case 2: If the first element of a row is zero.

• Example 1:

coeffs = [1 2 3 6 5 3];
Routh(coeffs)

• Example 2:

coeffs = [1 7 6 42 8 56];
Routh(coeffs)

• Example 3:

Gt = zpk([], [-2 -3 -5], 1000);
G = feedback(Gt, 1);
[~, den] = tfdata(G, 'v');
coeffs = round(den);
