说明：  信道极化图解，信道在经过极化后，有的性能接近1，有的接近0，保证正确(Channel polarization diagram: after the channel is polarized, some of the performances are close to 1, some are close to 0, ensuring the correctness)

劳斯稳定性判据的matlab实现。直接运行M文件，按提示输入特征多项式参数，即可进行系统稳定性判别。(The Routh-Hurwitz stability criterion is a necessary (and frequently sufficient) method to establish the stability of a single-input, single-output (SISO), linear time invariant (LTI) control system. More generally, given a polynomial, some calculations using only the coefficients of that polynomial can lead us to the conclusion that it is not stable. in this program you must give your system coefficents and the Routh-Hurwitz table would be shown )

基于分数阶的傅里叶变换，很详细、具体，欢迎各位还下载(Based on fractional order of Fourier transformation)

对时间序列或者信号进行fft谱分析，可以打开任意数据文件后分析，很方便使用。(FFT transfer of matlab code,it is useful for signal analysis.)

Sum of values ignoring NaNs

基于MATLAB，根据过往车辆磁场引起的磁场变化，识别车辆通过时刻，车辆类型(Based on MATLAB, the magnetic field caused by passing vehicles under the magnetic field changes, and identify through the moment, the types of vehicles)

一个混沌信号的产生程序，应该比较有用。请下载使用(A chaotic signal generation process should be more useful. Please download)

CentralDifference code for multi dimention strucures

对于排洪问题已给数据，对已有数据进行拟合并预测。(for flood relief problem,if giving data,it can be used to data fitting,and forecast the expectations.)

产生信号序列向量st,并显示st的时域波形和频谱 st=mstg 返回三路调幅信号相加形成的混合信号，长度N=800( Generated signal sequence vector st st time-domain waveform and the spectrum st = mstg return three AM signals are added to form the mixed-signal length N = 800)
