无功优化的最优潮流程序，可以自行替换ieee数据(Optimal Power Flow)

一种简单而快速的利用图像的轮廓在极坐标中的特征，做形状的匹配 matlab实现( a simple and fast image characteristics in polar coordinates, the outline of shape matching of matlab)

边缘检测Canny法的源程序,网上好像有人需要，所以就放上来了(Canny edge detection method of the source, the Internet seems to be any need, therefore Fangshanglai!)

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解，(This procedure Mr. Cheng a " Blocks" signal, and then adding white Gaussian noise, and then ' db3' wavelet decomposition,)

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: "Fractal basin boundaries and intermittency in the driven damped pendulum" E.

main_spheretoML是主程序，性能达到最大似然NL检测，调用了spheredecodetoML和spheredecodeinftoML两个子程序(sdinf ml)

discuss the cooling of a circular fin by means of convective heat transfer along its length. Convection gives rise to a temperature-dependent heat loss or sink term in the governing equation. Shown in Figure 4.9 is a cylindrical fin with uniform crosssectional area A. The base is at a temperature of 100°C (TB) and the end is insulated. The fin is exposed to an ambient temperature of 20°C
