语音信号处理，对输入的语音信号进行分帧处理，短时傅立叶变换，最后画出语谱图(Speech signal processing, the input voice signal processing sub-frame)

Newton optimization algorithm which uses gss algorithm as linesearch.

本程序是用COstas环跟踪信号的处理过程，具有较好的跟踪性能，(This procedure is used Costas loop tracking signal processing, has a good tracking performance,)

五点三次法实现振动信号趋势项的消除， 1、 计算出数据的均值、均方值、方差 ； 2、 用matlab编制五点三次法消趋势项程序。 3、 在同一坐标下绘出消趋势项前后时域信号，并分析比较。 绘出消趋势项前后信号的自相关函数。( Five points three times a method to achieve the elimination of the trend of the vibration signal, 1, to calculate the mean of the data, the mean square value, variance 2, the preparation of the five points three times France extinction trend procedure using matlab. 3, plotted in the same coordinate consumer trends before and after the time-domain signal, analyzed and compared. Draw to eliminate the trend before and after the signal autocorrelation function. )

包含多种小波变化，包括正交小波，双正交小波等，还有一些应用(Includes a variety of wavelet transform, including the orthogonal wavelet, biorthogonal wavelet, etc., there are some applications)

最佳离散信号及其设计在现代通信、雷达、声纳、制导以及信号处理、空间测控等领域中，扮演着越来越重要的角色。因此，深入研究最佳离散信号，具有重要的理论意义和应用意义。本代码在研究二值自相关二进阵列偶的理论基础上，设计了其搜索算法。(The best discrete signal and its design in the field of modern communications, radar, sonar, guidance and signal processing, spatial measurement and control plays an increasingly important role. Therefore, in-depth study the best discrete signal has important theoretical and practical significance. The code in the study binary binary array pairs based on the theory, design its search algorithm.)

对K-means聚类算法的改进X-means算法。针对K值如何设定的问题，利用BIC准则判断聚类点数量。同时附有两个初始聚类点的选择程序，自己选吧。(The improved X-means algorithm for K-means clustering algorithm. In view of the problem of how to set the K value, the number of clustering points is judged by the BIC criterion. At the same time, there are two initial clustering points of the selection program, choose it yourself.)

这是一个计算氨基酸物理化学性质的程序，可以用于研究蛋白质的性质(This is a calculation of physical and chemical properties of amino acid procedures, can be used to study the nature of protein)
