The dual window would be:

dual_window = np.zeros(2 * N)
x = np.cos(np.linspace(-np.pi, np.pi, 2 * M))
transitions = (1 + x) / (1 + x**2)
dual_window[(N + M) // 2:(3 * N - M) // 2] = 1
dual_window[(N - M) // 2:(N + M) // 2] = transitions[:M]
dual_window[(3 * N - M) // 2:(3 * N + M) // 2] = transitions[M:]
