信号与系统课程的Matlab编程指导，用于本科生教学和科研。(Signal and System Matlab Program)

仿真两个共振频率的冲击信号，观察其频谱分析(Impact signal simulation of two resonant frequencies observed spectral analysis)

用矩形窗设计一个FIR线性相位低通数字滤波器(Design a FIR linear-phase low-pass digital filter with a rectangular window)

基于光谱特征的提取算法，很实用，分类精度高(Based on spectral feature extraction algorithm, very practical, high classification accuracy)

快速傅里叶变换函数，自己写的函数，直接用即可，ceps倒频谱分析(fast folier transformation)

经验模态分解，依据数据自身的时间尺度特征来进行信号分解，给出本征函数。(Empirical mode decomposition, based on the data itself characteristic time scale for signal decomposition, given the intrinsic function.)

说明：  用MATLAB编写的运用Monte Carlo method数值积分的实例程序。可供初学者参考学习！(TETRAHEDRON_MONTE_CARLO is a MATLAB library which estimates the integral of a function over a tetrahedron using the Monte Carlo method. The library makes it relatively easy to compare different methods of producing sample points in the tetrahedron, and to vary the tetrahedron over which integration is carried out. )

face recognition for face and image processing system and pattern recognition

运用matlab编写，可用于一维信号压缩，经验证应用效果较好。(Using matlab prepared for one-dimensional signal compression, proven applications better.)
