一种基于 matlab 的电力系统仿真组件,用于电力系统潮流计算的软件的说明(See http://www.pserc.cornell.edu/matpower/ for more infomation)

最优潮流计算，matlab版，希望对电力系统仿真的同志有用！(OPF, Matlab version, and I hope to the power system simulation comrades useful!)

该matlab函数可以在matlab环境下读取pgm文件(To read the file of pgm format)

任意波形源的pwm信号生成电路控制桥式结构 其中上面是双极式调制pwm考虑了上下桥臂不能同时开通（加了延迟）；下面是受限单极式调制pwm信号发生器(Pwm arbitrary waveform signal generating circuit bridge structure wherein the control source is a bipolar modulator pwm at the upper and lower arms can be considered simultaneously opened (with delay) following is limited single modulator pwm signal generator)

数值计算中Jacobi迭代法的Matlab程序 (numerical calculation Jacobi iteration of the Matlab program)

说明：  《先进PID控制及matlab仿真》一书的源程序(&quot Advanced PID Control and matlab simulation&quot of the source book)

小波分析理论与MATALB R2007 实现第十二章演示代码(Wavelet analysis theory and MATALB R2007 A Chapter 12 demo code)

粒子群算法 最初版本，输入函数就可，fitness为目标函数(The initial version of the particle swarm algorithm, the input function can be objective function, fitness)

说明：  分数傅里叶变换以及计算全息图的迂回编码实现，以及衍射的仿真和所需的计算机生成图形。对信息光学的研究人员有用处。(Fractional Fourier Transform and circuitous CGH Coding and diffraction simulation and the required computer-generated graphics. Optics researchers in information useful.)
