This is a matlab version of 3D MSER, while VLFEAT library is required.

s变换，是当前比较流行的时频分析算法，可以用于地震数据时频分析和频谱分析，该程序基于matlab平台，实现了s变换和反变换。(s transformation, is the more popular time-frequency analysis algorithms, can be used for seismic data analysis and time-frequency spectrum analysis, the program based on matlab platform realize the s transform and inverse transform.)

说明：  基于Matlab的用Prim算法求解最小生成树问题(Prim-based algorithm using Matlab' s minimum spanning tree problem)

当M=4时，QAM的蒙特卡罗仿真程序，绘出误符号率和误码率曲线，并和理论曲线比较。(When M = 4 Shi, QAM of the Monte Carlo simulation program, draw the symbol error rate and bit error rate curve, and and the theoretical curves.)

基于matlab平台实现,可以实现模式识别领域的数据的分类及回归，一个很有用的程序。( Based on matlab platform, You can achieve data classification and regression pattern recognition, A very useful program.)

MUSIC算法DO模拟2个独立窄带信号入射到均匀线阵上，信号间互不相关，与噪声相互独立，噪声为理想高斯白噪声，阵列的阵元数为10，快拍数为200。阵元间距为入射信号波长的1／2，信噪比为20dB，信号入射角度差分别为5°，10°，20°。(DO MUSIC algorithm simulate two independent narrowband signals incident on the ULA, among signal unrelated, independent noise, the noise is ideal Gaussian white noise, the number of array elements of the array is 10, the number of snapshots to 200. Element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB, the signal difference between the angle of incidence was 5 °, 10 °, 20 °.)
