利用特别功能找出完美的符合。非常有用的程序。。(this is a very useful tool to find hht which is hilbert trans,)

说明：  burg算法对现代谱进行估计伯格算法（burg algorithm)一种直接由已知的时间信号序列计算功率谱估计值的递推算法。由于是J．P·伯格提出的，故得名伯格算法。(Burg algorithm is a recursive algorithm which can calculate the power spectrum estimation directly from the known time signal sequence. Because it is proposed by J.P. Berg, it is named Berger algorithm.)

说明：  高斯消去法 用列主元求解AX=b 数值计算实习 例子(Gaussian elimination)

说明：  iris fisher classifier

凸优化中牛顿下降法的matlab实现程序。(Convex Optimization in Newton descent method matlab implementation program.)

在缝后添加偏振片，输入两个偏振片透光轴与光波振动方向之间的角度，观察干涉现象。(Polarizer is added after the slit to observe the interference phenomenon)

说明：  该方法自适应地将一个复杂的非平稳的多分量信号分解为若干个瞬时频率具有物理意义的乘积函数（Product function,简称PF）之和，其中每一个PF分量由一个包络信号和一个纯调频信号直接求出。包络信号就是该PF分量的瞬时幅值，而PF分量的瞬时频率则可以由纯调频信号直接求出，进一步将所有PF分量的瞬时幅值和瞬时频率组合，便可以得到原始信号的完整的时频分布。(This method adaptively decomposes a complex non-stationary multi-component signal into the sum of several product functions (PF) with physical meanings at instantaneous frequencies, where each PF component consists of an envelope signal and a pure The FM signal is directly obtained. The envelope signal is the instantaneous amplitude of the PF component, and the instantaneous frequency of the PF component can be directly obtained from the pure frequency modulation signal. Further, the instantaneous amplitude of all PF components and the instantaneous frequency are combined to obtain the complete original signal. Time-frequency distribution.)
