Description: This simulink model simulates the damped driven pendulum, showing it s chaotic motion.
theta = angle of pendulum
omega = (d/dt)theta = angular velocity
Gamma(t) = gcos(phi) = Force
omega_d = (d/dt) phi
Gamma(t) = (d/dt)omega + omega/Q + sin(theta)
Play with the initial conditions (omega_0, theta_0, phi_0 = omega(t=0), theta(t=0), phi(t=0)) and the system parameters (g, Q, omega_d) and the solver parameters/method.
Chaos can be seen for Q=2, omega_d=w/3.
The program outputs to Matlab time, theta(time) & omega(time).
Plot the phase space via:
plot(mod(theta+pi, 2*pi)-pi, omega, . )
Plot the Poincare sections using:
t_P = (0:2*pi/omega_d:max(time))
plot(mod(spline(time, theta+pi, t_P), 2*pi)-pi, spline(time, omega, t_P), . )
System is described in:

Description: 设P(m,n)是初始控制点列，即原曲面的点（m行n列）。Q(m,n)是一次细分后得到的曲面的控制节点。
此函数采用Catmull-Clark细分曲面算法，对双三次B样条曲面细分,即m=n=4。
利用我们在13章第四节学过的知识，有公式MQM =SMPM S ,其中M，S可由课件知
构造初始控制点列（p1,p2)，其中p1是P的行坐标，p2是P的列坐标
-Let P (m, n) is the initial control point of the column, i.e. the original surface of the point (m rows n columns). Q (m, n) is the control node of the surfaces one after subdivision. This function takes a Catmull-Clark subdivision surface algorithm, the bi-cubic B-spline surface subdivision, ie m = n = 4. Using knowledge in Chapter 13, section IV, formula MQM, ' = SMPM' S' , wherein M, S by courseware known structure the initial control point of the column (p1, p2), where p1 is the row coordinate of P, p2 column coordinates of P
