说明：  matlab下饼图的绘制 .(matlab drawing under the pie.)

its about quaternion formation

车道线检测的matlab实现，能够准确实现车道线，通过霍夫变换。(Lane line detection matlab implementation, it is possible to achieve accurate lane by Hough transform.)

this code implements a dwt watermarking schema

可变次数的 曲线拟合 最小二乘算法实现 (Variable number of least squares curve fitting algorithm)

说明：  改进的差分粒子群算法，并用于求函数极值，程序中分别于DE PSO 蛙跳进行对比，结果显示，改进的差分粒子群更好(The improved Differential Particle Swarm Optimization (DPSO) algorithm is used to find the function extremum. The program is compared with DE PSO frog jump, and the results show that the improved DPSO is better.)

对两种调相方法进行分析比较,通过MATLAB编程对比两种方式的区别与联系(Phase modulation of two methods of analysis and comparison, through MATLAB programming in two ways the difference between contrast and contact)

Matlab code for calculation of spectrum density of G729 coder

直接序列扩频就是直接用具有高码率的扩频码序列在发端去扩展信号的频谱。而在收端，用相同的扩频码序列去进行解扩还原成原始的信息。(Direct Sequence Spread Spectrum is the direct use of the spreading code sequence with a high rate in the originator to expand the spectrum of the signal. Receiving end, using the same spreading code sequence to despread the broadening of the spread spectrum signal to restore the original information.)

很多种算法！！！解压了您能看到！很全面！ 此文件夹中的文件，如需被利用，则要直接放至work目录下 “最短路径”中的程序为一个网友写的，我把它改编为函数，放在“最短路和次短路中”，与次短路的程序并列，因为要求次短路，首先要求出最短路。 (A variety of algorithms! ! ! Extract you can see! Very comprehensive! This file in the folder, For use, will have to be directly released to the work directory Program in the "shortest path" for a net friend, and I adapted it to function on most short-circuit and short circuit in the "tied to short-circuit, the procedures to the requirements of times short-circuit, the shortest path first asked. )
