客观现实的另一类力学模型是弹性体(也称连续系统或分布参数系统)，它的物理参数是分布型的，具有无限多个自由度，且运动规律由偏微分方程来确定(Another kind of objective reality mechanical model is elastomer (also called the continuous system or distributed parameter systems), its physical parameter is the distribution model, with an infinite multiple degrees of freedom, and movement rules by partial differential equations to determine )

该书基于matlab编程来实现阵列天线方向图的形成(The book based on the matlab programming to achieve the formation of array antenna pattern)

this code is about mlp 1 layer neural network with back propagation training algorithm by using geradient descence for nonlinear system. input data are random.

说明：  根据最大相关性，最小冗余性的原则来优化特征空间结构(According to the principle of maximum correlation and minimum redundancy, the feature space structure is optimized)
