将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。(Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some paragraphs to realize the encryption of sound files. First, the first reading of a voice signal, the signal was 1024 points FFT transform, check after the completion point, divided into four vectors, the four vectors form a matrix, then for each vector transpose, re-integration, which will achieve a return to close the process.)

支持向量机和BP神经网络虽然都可以用来做非线性回归，但它们所基于的理论基础不同，回归的机理也不相同。支持向量机基于结构风险最小化理论，普遍认为其泛化能力要比神经网络的强。为了验证这种观点，本文编写了支持向量机非线性回归的通用Matlab程序和基于神经网络工具箱的BP神经网络仿真模块，仿真结果证实，支持向量机做非线性回归不仅泛化能力强于BP网络，而且能避免神经网络的固有缺陷——训练结果不稳定。 (Support Vector Machine and BP neural network, even though there can be used to make non-linear regression, but they are based on the theoretical basis for the different, the mechanism of regression is not the same. Support vector machine based on structural risk minimization theory, generally considered the generalization ability of neural networks than the strong. To test this view, the paper prepared by non-linear regression support vector machine procedures and based on a common Matlab neural network toolbox of BP neural network )
