四元数的隆戈库塔法，利用隆戈库塔队四元数进行更新，可以从中提取出载体姿态信息(Quaternion Longo Kutta method, using Longo Coulthard team quaternion update, can be extracted from vector-profile information)

绝对的lowe老人家提出的sift算法源码，配套有文档说明，对于初学者极度有用，还有我添加的注释我移植的仿射变换函数，绝对值得下的资源~！(The absolute lowe elderly sift algorithm proposed source code, supporting have documented for beginners extremely useful, and I add comments I transplanted affine transformation function, absolute worthy resource ~!)

说明：  高通滤波器，带通滤波器，数字FIR滤波器(The Shannon entropy is a measure of the average information content one is missing when one does not know the value of the random variable. The concept was introduced by Claude E. Shannon in his 1948 paper "A Mathematical Theory of Communication". Shannon s entropy represents an absolute limit on the best possible lossless compression of any communication, under certain constraints: treating messages to be encoded as a sequence of independent and identically-distributed random variables, Shannon s source coding theorem shows that, in the limit, the average length of the shortest possible representation to encode the messages in a given alphabet is their entropy divided by the logarithm of the number of symbols in the target alphabet. )

说明：  自己写的算术编码的matlab程序,内容是把自己的名字(当然也可以是其他的文字)用算术编码编码后再解码,有详细注释.给初学编码的朋友一些参考.谢谢.(Write matlab arithmetic coding procedure is to divide his name (of course also be other text) and then decode encoded using arithmetic coding, a detailed comment. Beginners encoding a friend to some reference. Thank you.)

Matlab 语言编写的用于彩色分割，边缘检测，基于区域生长的图像分割(Matlab color segmentation，edge detection，region growing image segmentation.)

信道估计中所使用的关键程序希望对大家有帮助(Channel estimation used in the critical processes for all of us want to help)

本源码是在DAB系统中MPE封装开销的源代码。希望对大家有用。(The source code is in the DAB system overhead MPE source code package. Hope useful for everyone.)

EM算法计算混合高斯模型，可以计算三个参数。(Gaussian mixture model EM algorithm, three parameters can be calculated.)

说明：   这个函数可以产生阶越函数并且可以多次调用产生矩形函数(This function can generate the more function-order and can be multiple calls to generate the rectangular function)
