说明：  瑞利衰落信道的仿真,基础SoS法产生瑞利衰落，经过运行正确(Rayleigh fading channal)

求pp波和ps波反射系数。。。。。。。。。。。。。。。。(Seeking pp wave and ps wave reflection coefficient)

使用MATLAB语言编写的声音报警程序，用于监测(use MATLAB language编写的声音报警程序，用于监测)

用于小波瞬态特征提取,间断点的提取。首相经过数据滤波处理(wavlet)

说明：  算差分盒维数的matlab程序。 让窗口中的每个像素都对分数维作出贡献。首先,计算某一尺度窗口的平均灰度值 ,然后判断每一个像素的灰度 ,若大于灰度平均值 ,则累加其灰度值为 max ,若小于灰度平均值 ,则累加其灰度值为min ,用max 和min代替 在 Sarkar 和 Chaudhuri 算法中的最大值和最小值 ,再通过拟合求出分数维。 (Differential count box dimension matlab program. Let window on the fractal dimension of each pixel to contribute. First, the calculation of an average gray scale of the window, and then determine the gray scale of each pixel, if the intensity is greater than the average, the cumulative value of its gray max, if less than the average gray level, the accumulation of its gray value of min, max and min to use instead of the algorithm in Sarkar and Chaudhuri maximum and minimum, and then by fitting the calculated fractal dimension.)

全变差去噪的标准matlab代码实现[ROF92],与Guy Gilboa的Texture preserving TV denoising [GSZ03] (total variation denoising standard Matlab code to achieve [ROF92] Guy Gilboa and the Texture preserving TV denoising [ GSZ03])

旅行商问题（Travelling Salesman Problem, 简记TSP):假设有一个旅行商人要拜访n个城市，他必须选择所要走的路径，路经的限制是每个城市只能拜访一次，而且最后要回到原来出发的城市。路径的选择目标是要求得的路径路程为所有路径之中的最小值。 此处使用蚁群算法求解TSP问题(Suppose a business trip to visit n cities, he must choose the path to go, pass through the restriction is to visit each city only once, and finally go back to the original departure city. Path selection objective is to get the path distance to the minimum value among all paths.Here,we use the procedure of ant colony algorithm to work out the TSP.)
