pi/4DQPSK调制解调程序，解调使用的是差分解调算法。(pi/4 DQPSK modulation and demodulation)

matlab simulation of a pulse generator

Powerbuilder Example ( DataCollection )

国际通用标准循环工况，可用于matlab车速仿真数据(International common standard cycle conditions, can be used for matlab vehicle speed simulation data)

实现快速傅里叶变换，自编函数FFT.而不需使用matlab自带的FFT函数(it can realize the fast fuleir tansform)

时频分析中维格纳 分布 ，以及维格纳分布的改进方法！( Joint Time-Frequency Analysis)

this is the lorenz atractor

For all classifier needs feature classification object .Here the program for height and width feature taken hand image.This program suitable for any single object in the image. input gray_img : input hand image or any measure image like 2d with 0 to 255 intensity output height : pixel count of height width : pixel count of width out_img : segmented image with line for height and width hand_height_width function implements hand height and width of the image using the method outlined in: calculate the hand height and width value for gray image. In Proceedings of the Information Sciences 275 (2014) 45–56. Hand shape identification on multirange images. [ height width out_img ] = hand_height_width ( gray_img ) function is to find the hand height and width value of the image. The input is given to the gray scale image.

本代码可不用借助其他工具直接对光子晶体光纤的色散等直接计算，对学习pcf的朋友很有帮助！(This code can be without the help of other tools directly on the photonic crystal fiber dispersion and other direct calculation, learning pcf helpful friends!)

this is the clustering matlab code, have a nice day!
