计算多层薄膜反射率程序，适用于光学薄膜设计或薄膜测量(Calculation of multi-layer film reflectivity procedures applicable to the design of optical thin film or thin film measurement)

FSK实现，对数据的调制和解调，加入高斯白噪声，最后产生眼图。(FSK implementation, the data modulation and demodulation, add Gaussian white noise, and finally generate the eye diagram.)

数值积分方法练习与函数调用：利用ode23或ode45求解线性时不变系统微分方程 =Ay(t)并绘出y（t）的曲线，式中 =0， =4 (Using ode45 ode23 or to solve the linear differential equation when the same system = Ay (t) and draw y (t) curve, type = 0, = 4 )

本去噪程序包，包含了多种小波阈值去噪算法，包含了小波变换算法的具体实现，去噪算法的具体实现，提供了一个统一的界面，便于初学者学习(this denoise package,includes servel kinds of denoise method that based on threshlod,and it has detail realization of wavelet transform,denoise method,GUI.it is convevient for beginners)

用于拉曼光谱的数据处理，有光谱的平滑和数据校正等代码(Data processing for Raman spectroscopy, spectral smoothing and data correction)

Non-decimated wavelet transform, redundant wavelet transform, stationary ％ wavelet transform(Non-decimated wavelet transform, redundant wavelet transform, stationary wavelet transform)

使用lingo求旅游商问题。 当然，如果数据量大的话，还是用经典算法吧。(Tourism operators seek to use lingo problem. Of course, if the data is large, then it is the classical algorithm used.)
