在Matlab中利用复合梯形公式和复合辛普森公式编程计算二重积分。(In Matlab, using the composite trapezoidal formula and calculate the double integral composite Simpson formula programming.)

Normalization from irregualr points

Program to read data from a Ball&Hoop system and plot a graph.

说明：  We describe a new method for performing a nonlinear form of Principal Component Anal

对具有随机噪声的二阶系统的模型辨识，进行标幺化以后系统的参考模型差分方程为 (7.90) 式中， 为随机噪声。由于神经网络的输出最大为1，所以，被辨识的系统应先标幺化，这里标幺化系数为5。利用图7.5正向建模(并联辨识)结构，神经网络选用3-9-9-1型，即输入层i，隐层j包括2级，输出层k的节点个数分别为3、9、9、1个； (Model identification of two order systems with stochastic noise)

多信道测量时，处理系统非理想特性的去嵌入程序。(the de-embedding code for a real communication system when doing channel estimation.)

根据多行三列的实验数据（x,y,signal)作出contourf图。其中x,y为二位空间位置（或其他概念的二维），signal为在该位置的信号。此代码先将数据按位置不同求平均，再将signal按照其对应的x,y分配到二位矩阵内。最后作图。编这个代码的初衷是为了制作大脑hippocampus区域place cell 活动性的contour 图。(it s a code i made for plotting a contour graph of experimental data (x,y,signal). The data should be n*3 arrays which cannot be plot into contour directly. In fact, it can subplot 6*6 graphs or more, but speed might be slow..... especially, when you want more detailed graphs.)

Good file to test for nothing.
