camshift算法matlab版，挺不错的源代码程序，有助于大家相互学习讨论(camshift algorithm matlab version, very good program source code to help everyone learn from each other to discuss)

比较生存曲线可以用统计假设测试日志秩检验。它是用来测试的零假设，没有任何区别的人口的生存曲线（即概率事件发生在任何时间点是相同的每个人口）.这个函数使用卡普兰曲线的程序来估计生存函数.(Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population). This function use the Kaplan-Meier procedure to estimate the survival function, so it is mandatory to download )

FSK调制解调程序，中频是15Mhz的，一个码元采样点250个(FSK modulation and demodulation process, 15Mhz IF yes, a symbol 250 sampling points)

说明：  FFT实现频谱图FFT实现频谱图 FFT实现频谱图FFT实现频谱图(FFT FFT FFT)

在matlab环境下，产生M序列及逆M序列，并画图进行比较(Matlab environment, to generate M sequences and inverse M sequence, and drawing comparison)

说明：  ARIMA 模型是在平稳的时间序列基础上建立起来的，因此时间序列的平稳性是建模的重要前提。检验时间序列模型平稳的方法一般采用 ADF 单位根检验模型去检验。当然如果时间序列不稳定，也可以通过一些操作去使得时间序列稳定（比如取对数，差分），然后进行 ARIMA 模型预测，得到稳定的时间序列的预测结果，然后对预测结果进行之前使序列稳定的操作的逆操作（取指数，差分的逆操作），就可以得到原始数据的预测结果。(time series prediction ARIMA)

本文件是DTMF信号采用卷积法进行解码的源程序，可以解码到DTMF信号的原始频率。(This document is a DTMF signal is decoded by convolution of the source, you can decode the DTMF signal to the original frequency.)

说明：  计算方法：函数平方逼近多项式的均方误差计算(Calculation method: function square mean square error of approximation calculation of polynomial)

mm1队列的仿真，还得出了统计给定到达率和离去率条件下系统的平均队列长度和平均等待时间，并与理论结果进行比对。(MM1 queue of simulation, it reaches a statistics given arrival rate and leave rate of the system under the condition of the average queue length and waiting time, on average, and the results compared with the theory. )
