利用prewitt、sobel、roberts边缘检测器进行边缘检测(Use prewitt, sobel, roberts edge detector for edge detection)

有约束最优化问题：利用matlab中已有的函数。举了一个利用里面函数求最小值的例子。这是最优化与运筹学中会经常遇到的问题(Constrained optimization problem: using the matlab existing function. For a use inside function minimise example. This was the optimized and operations research will often encounter problems )

在每一次小波变换中，都提取其中的“逼近信号”作为下次变换的输入，同时忽略掉其中的“细节信号”，即清除一次信号中包含的高频噪声分量。变换后的输出信号与原始信号相比，噪声起伏明显改善。(In every wavelet transform are extracted one of the " approximation signal" as the input of the next change, while ignoring one of the " details of the signal" , that is, a clear signal contains high frequency noise components. Transformed output signal compared with the original signal and noise fluctuations significantly improved.)

Use weka in matlab, call all the classifier in weka

线性时不变离散时间系统的频域分析传输函数和频率响应，(Linear time-invariant discrete-time system transfer function and frequency domain analysis of frequency response,)

基于粒子群算法的pid控制，MATLAB仿真(Based on Particle Swarm Optimization pid control, MATLAB simulation)

这个例子示出了充放电时的超级电容器的模式。该电路示出了与电池超级电容器的一个简单的杂交。超级电容器被连接到降压/升压转换器和电池连接到升压转换器。电池的功率由一个速率限制器块，因此瞬态功率由超级电容器供给到DC总线限制。(This example shows the supercapacitor model during charge and discharge. The circuit illustrates a simple hybridization of a supercapacitor with a battery. The supercapacitor is connected to a Buck/Boost converter and the battery is connected to a Boost converter. Power of the battery is limited by a rate limiter block, therefore the transient power is supplied to the DC bus by the supercapacitor.)
