估算能量谱，并且能通过圆滑对多道地震数据计算平均能量谱。(Power spectrum estimate by smoothing the periodogram. For more than one trace provides the average spectrum followed by smoothing.)

说明：  用newton迭代法求方程根的源代码 给出了newton迭代法的实现(with chemotherapy iterative method for equation of the source code is given to the Newton iterative method to achieve)

FCM算法是一种基于划分的聚类算法，它的思想就是使得被划分到同一簇的对象之间相似度最大，而不同簇之间的相似度最小。模糊C均值算法是普通C均值算法的改进，普通C均值算法对于数据的划分是硬性的，而FCM则是一种柔性的模糊划分(FCM algorithm is a clustering algorithm based on the division, which makes the idea is to be divided into clusters with the greatest similarity between the object, and the similarity between different cluster minimum. Fuzzy C-means algorithm is an ordinary C-means algorithm, the general C-means algorithm for the data are divided into hard and fast, and FCM is a soft fuzzy partition)

说明：  计算mfcc的函数，mfcc在音频分类中相当重要(Mfcc function calculation, mfcc very important in the audio category)

压缩包内全是基于matlab解决线性规划的问题的解法和例题，通过简单的例题可以总结出很好的适合你的程序(All compressed within matlab solution to solve linear programming problems and examples, can be summed up by the simple example of a good fit for your program)

the codes which i sent contains matlab code for encryption using 4 out of 8 code,binary to decimal conversion,decimal to binary conversion,subband coding,upsampling.

说明：  系统介绍了几种常用的小波变换程序（matlab）(The file introduces some common wavelet transformation programs )

各种随机分布的直方图，频谱估计图，频谱归一图(Various random distribution histogram, spectrum estimation map, the normalized frequency spectrum chart)
