g729的编码和解码程序，matlab写的编解码是分开的(G729 encoding and decoding procedures, matlab codec is written in separate)

支持向量机非线性回归通用matlab程序，本程序使用支持向量机法，实现对数据的非线性回归，核函数的设定和修改在函数内部进行，数据预处理在函数外部进行，简单易懂，希望能对大家有所帮助(Universal non-linear regression support vector machine matlab program, this program uses support vector machine method to achieve non-linear regression of data, settings and modify the kernel function within the function, the data pre-processing function externally, simple and easy to to understand, hoping to be helpful to everyone)

设一个小孩在平面上沿着某曲线行走，此曲线由时间参数曲线确定。假设小孩借助于一个长度为 的硬木棒拖着或推着一个玩具，试求玩具的平面轨迹。(set up a child in a plane curve walk along this curve by the time parameter curve. Using a hypothetical child for the length of the hard wooden dragging or pushing a toy, toys trial for the plane trajectory.)

randgen(mu,mu1,mu2,cov1,cov2,cov3) = Random generation of Gaussian Samples in d-dimensions where d = 2 mu, mu1, mu2 = (x,y) coordinates(means) that the gaussian samples are centered around cov1, cov2, cov3 are the covariance matrices and will vary changing the shape of the distribution, example: cov = sigma^2*Identity Matrix, where sigma^2 = a scalar N = the number of gaussian samples used are provided as user input, A test set of N/2 and a training set of N/2 gaussian samples is also generated Output is directed to the command window and a plot of the distributions are generated
