In this text, students of applied mathematics, science and engineering are introduced to fundamental ways of thinking about the broad context of parallelism. The authors begin by giving the reader a deeper understanding of the issues through a genera

采用bp神经网络对其进行函数拟合。误差反向传播网络（bp网络）是目前人工神经网络模式中最具代表性，应用最广泛的一种模型，具有自学习、自组织、自适应和很强的非线性映射能力，可以以任意精度逼近任意连续函数。-The bp neural network to its function fitting. Error back propagation network (bp network) is the artificial neural network model of the most repres
