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.

matlab图像处理下的特定图像的识别与距离的测量(matlab image processing of the specific image recognition and distance measurement)

在matlab中很适用，很经典的产生几种测试噪声的程序。(In matlab it is applicable, it is the classic noise generated several test procedures.)

图像去噪中常用的RLO和对数模型源代码 自己编的 效果还可以(RLO commonly used in image denoising and model number of the effect of the source code can be compiled their own)

自适应滤波技术中的LMS自适应滤波器程序(Adaptive filtering technology LMS adaptive filter procedures)

WIND FORECASTING AND CHOOSING OF TIME SEIRES MODEL

小波域内选择能量较大的系数嵌入数字水印的程序(Digital watermarking based on block energy selection)

该模型能够通过准确的仿真光伏电池的输出特性，如p-v以及I-V的变化曲线(the character of pv)

说明：  PSO算法，通用性较强，只要换一下fitness就可以了(PSO algorithm, universal strong, as long as a change in fitness can be a)
