说明：  利用经典BP网络逼近一个多输入多输出的函数(The classical BP network to approach a multi-input multi-output function)

零相移滤波器m函数，优点是克服了滤波器产生的相位滞后，缺点是本仿真不能保证实时性，其原理为输入一次序列，正反各变换一遍。(Zero phase shift filter m function, the advantages of the filter to overcome the phase lag, the disadvantage is that the simulation can not guarantee real-time, the principle of the input sequence, the pros and cons of each conversion.)

说明：  支持向量机工具箱可直接使用，包含支持向量机各个函数(Support Vector Machine Toolbox can be used directly, including various functions of support vector machine)
