自编的倒频谱代码。倒频谱（信号）是信号频谱取对数的傅立叶变换后的新频谱（信号），有时候会称频谱的倒频谱(A cepstrum is the result of taking the Inverse Fourier transform (IFT) of the logarithm of the estimated spectrum of a signal)

圆形天线阵列MUSIC算法的matlab实现，有详细注释(Circular antenna array MUSIC algorithm matlab realize, there are detailed notes)

提供了外文文献具体解释了HHT得缺陷之一，模态混叠现象。 通过matlab的仿真具体解释了HHT用于信号分析时出现模态混叠的临界点。(english papers to explain one of the limitations of HHT-MODE MIXING simulation base on MATLAB provide graph to improve that limitation)

图像处理中基于小波变换的快速边缘检测matlab实现(Image processing based on wavelet transform to achieve fast edge detection matlab)

参数假设检验：对差异进行定量的分析，确定其性质，是随机误差还是系统误差.为给出两者界限，找一检验统计量T，在H0成立下其分布已知。(Parameter hypothesis test: a quantitative analysis of the differences, to determine its nature, is random error or system error. Is given two boundaries, looking for a test statistic T, its distribution under the establishment of the H0 known.)
