模式分类中基于BP神经网络的曲线拟合；根据BP神经网络的模型，调用MATLAB工具箱函数，通过对样本数据进行训练，对测试样本数据进行成功的预测，预测的输出值与实际值之间几乎没有偏差。-Pattern classification of curve fitting based on BP neural network　Based on BP neural network model, call MATLAB toolbox function, through the training sample data, the test sample data are successful prediction, prediction of almost no deviation between the output value and the actual value.
