说明：  状态空间模型　加强ＭＡＴＬＡＢ学习　很有用的 (state-space model to strengthen MATLAB very useful learning)

说明：  利用有限单元方法，采用三角形剖分，来求解场值(Finite element method, using triangulation to solve the field value)

Discontinuous Galerkin Methods Algorithms, Analysis, and Applications for Advec1D

计算二维图形的分形维数，比较好用，计算方便(Calculate the fractal dimension of a two-dimensional figure)

先归一化输入输出参数，用KMens优化RBF神经网络中心值，然后计算隐节点数据中心间的距离（矩阵），得到各隐节点的扩展常数（宽度），接着用最小二乘法得到各隐节点的输出权值，对数据进行反归一化，并绘图得到神经网络输出与测试集图，同时进行性能评价(First, the input and output parameters are normalized, the central value of the RBF neural network is optimized by KMens, then the distance (matrix) between the data centers of the hidden nodes is calculated, and the extended constant (width) of the hidden nodes is obtained. Then the output weights of the hidden nodes are obtained by the least square method, and the data are back normalized, and the neural network is drawn. Output and test set diagrams, and performance evaluation)

求时间序列的最大李亚普诺夫指数，很好用。(the largest lyapunov)
