6.Recursive-Methods

说明：  用于计算HURST指数的分形维数的MATLAB小程序，属于经典的。(HURST index used to calculate the fractal dimension of the MATLAB small procedures, are classic.)

Function to generate a voice signal, adding noise, and filtering to recover the original signal.

this is code for "embeded extended visual cryptography ". I had done programming in MATLAB. >>steps to run the program: Type add only in command window. I had run this code on Matlab 7.1

HI MATLAB CODE FOR RECEIVER DECODE AND TRANSMITTER

轨迹绘制。点击鼠标左键确定轨迹典型点，点击右键结束绘制。(Trajectory drawn. Click the left mouse button to determine the trajectory of a typical point, right-click to end the drawing.)

逻辑航迹起始算法代码，实现简单的逻辑算法(logical algorithm for Track initiation)

The second line simply displays the matched image, the third line gets the histogram of the matched image, and the last line plots the histogram, which should match the specified PDF. Remember the PDF is supplied to the histogram equalization function, not a CDF, it automatically creates a CDF from the PDF supplied to it.

用于时间序列的预测，包含序列特征描述、平稳性检验、序列周期判断、季节因子提取、指数平滑预测、及ARIMA预测(Sequence features for time series prediction, including the description of the stationary test, to determine the sequence cycle, seasonal factor extraction, exponential smoothing, and ARIMA forecasting)
