采用matlab语言实现现代信号处理，谱估计，AR模型法(Modern Signal Processing using AR model.)

SPIDER是测量超短脉冲的一种有效方法，该程序给出了基于Matlab的SPIDER代码，它可以直接运行。(SPIDER is one of the effective approaches to measure the pluse durantion.This program is the code of SPIDER based on Matlab.It can easily be ulited.)

DC-DC model with feedback control

Simple but effective example of "Region Growing" from a single seed point. The region is iteratively grown by comparing all unallocated neighbouring pixels to the region. The difference between a pixel s intensity value and the region s mean, is used as a measure of similarity. The pixel with the smallest difference measured this way is allocated to the region. This process stops when the intensity difference between region mean and new pixel becomes larger than a certain treshold

国外matlab，时间转换程序，层次清晰，有源代码，也有界面( Foreign matlab, time conversion process, the level of clarity, source code, there are interface)

已知采样频率80000，通带衰减0.5阻带衰减45 通带截止频率4000，阻带截止频率20000，用双线性变换法设计数字低通滤波器 (Known sampling frequency 80000, attenuation in the passband stop-band attenuation 45 0.5 Passband cutoff frequency of 4000, 20,000 stopband cutoff frequency, using bilinear transform design digital low-pass filter)

此代码主要是用simulink搭建的一个三电平SVPWM模型，能出图，实用型的一个代码。(This code is to use a three-level SVPWM simulink model structures, to a map, a practical code.)
