说明：  作为初学者的典范,但是程序有很些许错误，还希望高手指点，特别是运行时，每次出的结果不一样，更希望高手指点！(this project is just so so ,it can be used to study by the first learner!certainly ,there are some misstakes, but i can not find it ,because my level is just so so ,i hope you can correcting me !thank you very much !if you correct my project ,pleased send email to hljdx.wuyou@163.com ,thanks! i found my project ,there are so many results when i run ,i do not know why?)

说明：  灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system.)

用BP网络完成函数的逼近 P网络通常有一个或多个隐层，隐层中的神经元均采用sigmoid型变换函数，输出层的神经元采用纯线性变换函数。本例应用一个两层BP网络来完成函数逼近的任务，其中隐层的神经元个数是5。(network to be completed by BP function approximation P networks usually have one or more hidden layer, a hidden layer neurons are used sigmoid-type transformation function, the output layer neurons using pure linear transformation function. The application of a two-tier cases BP network function approximation to complete the task, hidden layer neuron number is 5.)
