基于simulink的西门子标准400V低压馈线模型，其中包含一个PV光伏并网模型(Based on the the simulink Siemens standard 400V low voltage feeder model, which contains a PV photovoltaic grid model)

canny算子,很有用的一个程序.容易掌握.(a simple and easy algorithm.)

This is traning by ica.

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.)

基带传输： 欲传送的01比特流 + 码型变换（HDB3码） + 基带成型网络（采用升余弦滚降系统）+ 信道 + 码型反变换 + 01比特流。 (Baseband transmission: To send the 01 bit stream+ code type transformation (HDB3 code)+ base-band forming network (with raised cosine roll-off system)++ code based channel inverse transform+ 01 bit stream.)

说明：  将图像从RGB颜色空间转换成lab颜色空间(Transfer image s color space from RGB to lab)

UWB1000模块测试所得数据初步处理之后，已知锚点的坐标，可利用该文件里的程序解算标签三维位置。(After preliminary processing of data obtained from UWB1000 module test, the coordinates of anchor points are known, and the program in this file can be used to calculate the three-dimensional position of tags.)

基于ORL和eigenface的一个人脸识别小程序，导师布置的作业，自己用matlab简单实现了下(Based on ORL and eigenface face recognition of a small program, the mentor assignments, they used a simple realization of the next matlab)

qpsk transmiter with qpska modulator QPSK is a method for transmitting digital information across an analog channel.Data bits are grouped into pairs, and each pair is represented by a particular waveform, called a symbol, to be sent across the channel after modulating the carrier.
