采用MATLAB编写B样条绘制程序，可以选择四种节点矢量，采用Deboor算法,详细参看计算机辅助几何设计的书籍(CAGD)(MATLAB used to prepare B-spline drawing program, you can choose the four-node vector, using Deboor algorithm, see the detailed computer-aided geometric design book (CAGD))

用matlab开发的gui，可以滚动显示字幕，经过验证，完全可行的，有兴趣的同学可以看一下。(Developed using matlab gui, you can scroll to display the subtitles, proven, fully feasible, students who are interested can look at.)

极限学习机（Extreme Learning Machine，ELM），该算法随机产生输入层与隐含层间的连接权值及隐含层神经元的阈值，且在训练过程中无需调整，只需要设置隐含层神经元的个数，便可以获得唯一的最优解。与传统的训练方法相比，该方法具有学习速度快、泛化性能好等优点(Extreme Learning Machine regression and classification, introduce a new algorithm for SLFN- Extreme Learning Machine (Extreme Learning Machine, ELM), the algorithm randomly generated input layer and hidden layer connection weights between the hidden layer and dollar threshold, and no adjustment in the training process, only need to set the number of hidden layer neurons, they can obtain a unique optimal solution.)
