LED单珠光源的特性对配光具有重要影响，本程序从配光要求这个角度对不同厂家的LED灯的质量进行分析。(the property of LED is very important for using, and the program can envalue the quality of LED light source.)

压缩感知算法中观测矩阵为哈达玛矩阵重构算法为OMP时的测量相对误差与观测矩阵维数的关系(Compressed sensing algorithm for the Hadamard matrix of observation matrix reconstruction algorithms for the OMP and the relative error when measuring the dimension of the relationship between the observed matrix)

m_map文件在MATLAB中非常重要，尤其是画与海洋以及地形有关的图中，但缺乏中文资料，这是对其英文的部分翻译(m_map file in MATLAB is very important, especially painting and oceans and terrain-related figure, but the lack of Chinese data, which is part of its English translation)

是关于于水声信道均衡的程序，主要用于降低误码率，优化水声信道的性能，减小码间干扰。(Are about in the water channel equalization procedure, mainly used to reduce the error rate, and optimize the acoustic channel performance, reduce inter-symbol interference.)

This code would calculate the approximate root of any polynomial using Newton Raphson Method
