数据模型归一化，模态振动，采用的是脉冲对消法，含噪脉冲信号进行相关检测,分析了该信号的时域、频域、倒谱，循环谱等,使用起来非常方便。( Normalized data model, modal vibration, It uses a pulse of consumer law, Noisy pulse correlation detection signal, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Very convenient to use.)

说明：  基于互质采样-分段相参积累多项式相位变换的微弱线性调频信号检测算法。该代码的相关论文以oral presentation的形式发表于2018年10月在南京举行的IET国际雷达会议。(Multi-component LFM parameter estimation via order-2 DPT (overlapping and coprime) Author: Dr. Shengheng LIU)

基于LSB的直接4bit替换法，就是直接用秘密图像像素值的高4bit去替换载体图像像素值的低4bit。 (Direct 4bit substitution, that is, the direct use of the secret image pixel values of the high-4bit image pixel value to replace the carrier' s low 4bit.)

中心极限定理和Box-Muller方法产生高斯噪声 并用于二进制双极性基带通信系统仿真(The central limit theorem and the Box-Muller method of Gaussian noise and used to generate a binary bipolar baseband communication system simulation)

計算Augmented Routh table的工具， 只須輸入由tf, zpk, ss, fdr建立的System Function， 程式會自動計算及顯示Routh table的數值。 (Augmented Routh table Calculation. AUG_ROUTH_TABLE=AUG_ROUTH(G) computes the augmented Routh table for a given system G (created with either TF, ZPK, SS, or FRD). )

给出一组表征年平均全球表面温度异常的数据“gsta.dat”。这组数据的第一列表示时间，第二列表示相应的数据值。(A given dataset “gsta.dat”, which is the annual mean global surface temperature anomaly. In “gsta.dat”, the first column is the time and the second is the corresponding data value.)

The code demonstrate morphing that is basically source image warping followed by cross dissolving.
