说明：  这是一个预测很多东西都可以的预测程序，但是我没有编好，谢谢啊(This is a lot of things can forecast the forecasting process, but I do not for good, thank you ah)

hidden markov chain model

fast fourier transform

Function of Weighted Low Pass Filter.

点目标线性调频连续波fmcw差频信号仿真(Point target fmcw difference frequency signal simulation)

实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)

说明：  K-means聚类，将多个点根据各自的坐标，一定的算法分析，在matlab上可以看到聚类结果图像，帮助人们更好的分类不同的点，确定选址问题(K-means clustering, according to the coordinates of multiple points, a certain algorithm analysis, in Matlab can see the clustering results image, help people better classify different points, determine the location problem.)

计算信号的峰值，平均值和均方根值，并从txt文件直接得到(get the top and its mean value)
