FUNCTION SQUARE WITH SIMULINK

uses the forward difference method for a European call.

Sunspot activity is cyclical, reaching a maximum about every 11 years. Let s confirm that. Here is a plot of a quantity called the Zurich sunspot relative number, which measures both number and size of sunspots. Astronomers have tabulated this number for almost 300 years.

说明：  利用MATLAB产生正弦信号，加入高斯白噪声后利用小波变换技术去噪声(The sine signal is generated by MATLAB, and the noise is removed by wavelet transform after Gaussian white noise is added)

这组代码模拟了整个信号的编码，调制，解调，译码在无线通信，其中包括A-law扩展，PCM和的2PSK调制解调的技术过程。(This collection of codes simulates the whole signal encoding, modulation, demodulation, decoding process in wireless communication, which involves the techniques of A law companding, PCM, and 2PSK modulation and demodulation.)

与传统的小波分解相比，提升小波可以实现整数小波变换，其方法与一般去噪法相同，都是对小波分解的高频系数进行阈值量化来达到去噪的目的。(Compared with the traditional wavelet, lifting wavelet can achieve integer wavelet transform, its the same way as regular de-noising method, are the high-frequency coefficients of wavelet decomposition threshold quantization to achieve the purpose of de-noising.)

特征点提取，一个关于harris算子提取图像特征的程序。。 做了些许改动(Feature point extracting，Harris operator on image feature extraction process. . Make a few changes )
