本文介绍了基于matlab 的径向基函数RBF 神经网络对于图书馆借书量预测的方法，讨论了RBF 神经网络的构造思路、参数和分布密度spread 的选择。为图书馆工作人员书籍管理提供了新的思路。[关键字]：matlab RBF 神经网络样本 分布密度[Abstract]：A brief introduction of the means using the radial function RBF Neural Networkbased on the matlab, which can help to predict the volume lent from the library. This article also discusses the constructive means, parameter and the choice of the distributing density, thus, providing the library staff with a new means of the rationality of the books management.[Key words]：matlab radial basis function neural network sample distributing density
