LT码编码程序，此函数生成LT码的编译码矩阵，并完成LT编码过程，生成编码符号序列( has marked the various parameters)

对于给定的结构振动响应数据（时间序列信号）， 该程序可以分解成多个订单这些响应信号 小波子信号，然后计算出分信号能量spectum。 (For a given structural vibration response data (time series), the program can be decomposed into multiple sub-orders for the response signal wavelet signal, and then calculate the sub-signal energy spectum.)

TV 重建工具箱，用于处理图像的去噪，去模糊，修补等，是很好的学习工具。(TV rebuild Toolbox for denoising image to blur, repair, etc., is a good learning tool.)

说明：  image task 1 by me and my friend

仿真火车站的站场图，可以办理进路，显示信号机，单操，单锁道岔等功能(Simulation Station station map, you can handle into the road.)

基于传输矩阵法的对布拉格光纤光栅反射谱的仿真研究(Fiber Bragg Grating Simulation of reflection spectra based on Transfer matrix method )

该程序是基于小波变换的熵谱，用来提取时间序列的周期成分。熵谱相对于小波谱来说在提取周期成分上有一定优势(The program is based on spectral entropy of wavelet transform to extract time series of the periodic component. Entropy is relative to the small spectral component in the extraction cycle, there are some advantages)

产生随机信号并通过低通滤波器 计算其统计参数Any changes made cards can be good results(Random signal generated by low-pass filter to calculate the statistical parameters)

说明：  在Matlab环境下模拟布朗运动的产生，加强对随机现象的理解。(Environment in Matlab simulation of Brownian motion and enhance the understanding of random phenomena.)
