Find local minimum in matlab

信号与系统第二版作者是Steven T. Karris。全书分为基本信号表述，拉普拉斯变换，反拉普拉斯变换，电路分析，脉冲响应等章节。(Signals and Systems 2nd edition written by Steven T. Karris. The book is divided into basic signal representation, Laplace transform, anti-Laplace transform, circuit analysis, impulse response and other sections.)

50kW，380V，50HZ的负荷通过AC-DC-AC变换器连接到25kV，60Hz电网上。该电源由两个电压源型变换器和一个直流电容构成。(A 50 kW, 380 V, 50 Hz load is connected to a 25 kV, 60 Hz grid through a AC-DC-AC power supply. This power supply consists of two voltage source converters, VSC1 and VSC2, connected through a DC link.)

粒子群代码,是一个简单的例子群算法，maltab。可以根据需要进行修改，亲测过可以运行(Particle swarm code)

5节点的电力系统潮流计算，建立了发电机、变压器、输电线路和负荷模块，使用典型参数计算得到的电压、相位、有功和无功显示清晰，便于分析和设计。(The node power flow calculation, generators, transformers, transmission lines and load module, calculated using the typical parameters voltage, phase, active and reactive clear, to facilitate the analysis and design.)

这个m代码包含了一系列的小波变换的实现函数，有Daubechies,symlets,splines,S+P小波, JPEG2000小波变换等. 可以进行1D或者二维小波变换。(The m code contains a series of wavelet transform to achieve function, and Daubechies, symlets, splines, S+ P wavelets, JPEG2000 and other wavelet transform. Can be 1D or two-dimensional wavelet transform.)

增强，计算目标个数及周长增强，计算目标个数及周长(Increased number of objects and calculate the circumference increased number of objects and calculate the perimeter)

我们做很多实验时得到的一些数字信号必须经过处理才能最终得到应用。此文件是matlab数字信号处理说明书，希望对读者有帮助(We do a lot of experiments to get some of the digital signal must be processed in order to ultimately be applied. This file is matlab digital signal processing instructions, hoping to help the reader)
