使用支持向量机进行非线性回归，得到非线性函数y=f(x1,x2,…,xn)的支持向量解析式，

求解二次规划时调用了优化工具箱的quadprog函数。本函数在程序入口处对数据进行了

[-1,1]的归一化处理，所以计算得到的回归解析式的系数是针对归一化数据的，仿真测

试需使用与本函数配套的Regression函数。-　Using non-linear support vector machine regression, nonlinear function y = f (x1, x2, ..., xn) support vector analytic,　Optimization Toolbox quadprog call function when solving quadratic programming. The function of the data in the program carried out at the entrance　[-1,1] of normalization, so the regression coefficients calculated analytical formula is for the normalization of data, simulation test　test need to use this function supporting The Regression functions.
