说明：  MATLAB中画椭圆的自定义函数：ellipse，用后才会发现这个函数的强大功能！ 在ellipse之函数当中，其输入之变数分别如下： -ra 椭圆之长轴半径，可为列矩阵，若为列矩阵时，代表可同时绘制许多椭圆。 -rb 椭圆之矩轴半径，可为列矩阵，如ra。 -ang 水平轴之倾斜角，以弧度表示。可为列矩阵，但ra、rb、ang三者之矩阵数应相同。 -x0,y0 圆心之座标，可为矩阵，若为矩阵时，代表可同时绘制许多不同圆心位置之椭圆。 -C 椭圆线之颜色 -Nb 绘椭圆时所用之点数。(MATLAB in the oval painting custom function: ellipse, will be found after using the power of this function! Ellipse of the function in which its input variables are as follows:-ra ellipse of major axis radius for the column matrix, if for the column matrix, a representative may at the same time drawing many elliptical. oval-rb-axis radius of the moment for column matrices, such as ra.-ang horizontal axis of the tilt angle to radians. Matrix for the column, but ra, rb, ang among several of the matrix should be the same.-x0, y0 the coordinates of the center for the matrix, if for the matrix, a representative may at the same time drawing a number of different oval center location.-C elliptic line color-Nb painted oval of points used.)

径向基函数神经网络的优点：逼近能力，分类能力和学习速度等方面都优于BP神经网络，结构简单、训练简洁、学习收敛速度快、能够逼近任意非线性函数，克服局部极小值问题。原因在于其参数初始化具有一定的方法，并非随机初始化。代码为RBF的matlab程序，可以使用但是需要自己配置数据。(Radial Basis Function Neural Network (RBF-NN) has the advantages of better approximation ability, classification ability and learning speed than BP Neural Network (BP Neural Network). It has simple structure, simple training, fast learning convergence, and can approximate any non-linear function to overcome the local minimum problem. The reason is that its parameter initialization has a certain method, not random initialization.)
