说明：  自己做的几个涉及到测量的子程序，有坐标反算、排序、角度转换、时间处理、四舍六入、三维显示等等(Yourself a few involves measurement subroutine, are calculated by coordinates, sorting, Angle conversion, time processing, and six into four, three dimensional display and so on)

说明：  基于matlab 的 iir高通滤波器设计，可以过滤150Hz以下的噪声；使用时把音频路径替换正自己的音频路径即可运行。(The design of IIR high pass filter based on Matlab can filter the noise below 150Hz; when using, the audio path in the file can be changed to its own path to run)

说明：  matlab代码，实现神经网络中的BP算法-误差反向传播算法，用于分类，拟合和非线性系统建模等多种问题(An example of BP neural network)

利用R的toepliz性质，是实数，则r也应该是实数，是实信号r(-m)=r(m)(Toepliz the nature of the use of R is real number, then r should be real, real signal r (-m) = r (m))

最小二乘法拟合，基于matlab的算法，拟合研究的一部分(LSF Least Square Fit )

大尺度信道衰落模型-室外信道模型-Okumura model(Large Scale Path Loss and Okumura Model)

use the conventional susan edge detector algorithm to detect the edges of a given image. in first step the given image will be filter.

指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延，即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)
