说明：  利用FDTD模拟光子晶体光纤中的色散的程序，是在wang.m程序基础上改进之后计算色散的。(FDTD simulation of photonic crystal fiber used in the dispersion of the procedure is based on the improvements in the program after wang.m calculated dispersion.)

用四元十字阵做被动声定位算法设计，现在是用matlab神经网络工具箱构建RBF神经网络然后仿真显示图形(With a four-element Array do passive acoustic localization algorithm design, now using matlab neural network toolbox and then build on RBF neural network simulation display graphics)

在matlab环境下，用simulink模块编程实现PID控制基本算法(In the matlab environment, using simulink module programming PID control of the basic algorithm)

是一些利用小波变换进行多源图像融合的程序 (Some wavelet transform image fusion process)

these are the Mtlab functions to plot the figures in the book Communication system (by Haykin)

去噪为仿真信号建立； 去噪1为eemd去噪； 去噪2为形态滤波器； 去噪3为小波去噪，全局阈值，给定阈值（软阈值，硬阈值）； 去噪4为实际去噪(2 for morphological filter denoising Denoising 3 as the wavelet denoising, global threshold, the given threshold (soft threshold and hard threshold) 4 for practical denoising denoising)

this archive is a document that us allows make a simulation of modulator sigma delta

前面搞错了,把五个文件一起打包上传了,现在一个一个传 贝塞尔Bassel滤波器的离散滤波算法 模拟程序 程序头上有详细的注释和使用说明(Made a mistake in front of the pack with five file upload, and now one by one Chuan Bassel filter discrete Bessel filter head simulation program procedures detailed notes and use)

说明：  太阳能光伏单相并网逆变器及仿真和一系列别的神马东西 (Solar photovoltaic grid-connected inverter and Simulation of single phase and a series of other what thing)
