说明：  用MATLAB语言实现MFCC特征参数提取(Using MATLAB language MFCC feature extraction)

《系统辨识及其MATLAB仿真》一书中第2、5、7章的原码。(" System Identification and MATLAB simulation,2，5，7 Chapter source )

进行PCA分解，由迭代算法，算出得分向量和负荷向量(something about PCA)

creates a list of all subdirectories of a specific folder

matlab程序，关于模糊神经网络的，编修正函数，五层网络(matlab program, compiled correction function, five network fuzzy neural network)

the maximum rate in function of the 02 probablity of detection and false alarm

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

说明：  计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)
