语音增强谱减法程序，已经运行成功，效果明显(Spectral subtraction speech enhancement program has been run successfully, obvious effect)

说明：  一个和数据库连接的差别矩阵matlab源代码，自己编写的，有需要的可以看看。(And the difference between a database connection matrix matlab source code, I have written, and there is a need that can take a look at.)

求第一个城市到其它城市的最短路径.用矩阵（为顶点个数）存放各边权的邻接矩阵，行向量、、、分别用来存放标号信息、标号顶点顺序、标号顶点索引、最短通路的值(The first city to find the shortest path to other cities. With a matrix (for the number of vertices) records of the right side of the adjacency matrix, row vector, were used to store label information and label the vertex order, label the vertex indexes, the shortest pathway value)

Code to calculate Rescaled Range Statistics

描述了单光子与腔内谐振子相互作用后，其输出频谱的一些特性，谐振子的量子状态(Describes the interaction of a single photon of the cavity, some of the characteristics of the output spectrum)

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。(Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR, the human ear can identify audio.)

Integers is given a rectangular matrix. define: 1) The number of rows containing at least one zero element 2) the number of the column in which the longest series of the same elements

一种数据挖掘分类算法的MATLAB实现。(classification in matlab.)

matlab下的电力系统可靠性评估算法，算例为RTS79(matlab under the power system reliability evaluation algorithm, numerical example is RTS79)

代码是matlab编写，有例图，可直接运行（注意修改路径）。主要用来检测桥面、路面裂纹，有详细函数功能说明和算法思想，实现了路面规则条纹背景的频率估计，采用频域滤波可有效去除路面图像接近估计频率的噪声，保留目标裂纹，实现了初步的检测功能，但是功能还不完善，可作Demo供大家参考。有兴趣的朋友可以逐步完善、移植，有兴趣的朋友请与我联系。(Matlab code is written, there is case diagram, can be run directly (Note to modify the path). Mainly used to detect bridge, road cracks, a detailed description and algorithms Function thinking to achieve a frequency of road rules striped background estimation, using frequency domain filtering can effectively remove the image close to estimate the frequency of road noise, keep cracking goal to achieve a preliminary detection function, but the function is not perfect, can be used for Demo for your reference. Interested friends can gradually improve, transplant, friends who are interested, please contact me.)
