拉格朗日内插法的matlab实现 改进后可用于多种用途(Matlab Lagrange interpolation method can be used to achieve the improved multi-purpose)

matlab和optisystem调试用的幅度调制程序，在optisystem里面使用matlab组件然后使用。(matlab and optisystem debugging with the amplitude modulation process, component and then use the optisystem inside Matlab.)

amplitude and fm modulation good for you

用于生成黑白测试条纹图，可用于普通2D显示或者3D显示器的测试与开发。(Can be used for testing displays.)

好用的互信息程序，可以计算时序信号的互信息以及熵等。可以直接使用(it is used for multil-information,and it can be used directly.)

说明：  用级数PI/4 = 1 -1/3 + 1/5 -1/7+…求PI的近似值，要求取前1000项来计算。(With a series PI/4 = 1-1/3+ 1/5-1/7+ ... seeking an approximation of PI, demanded before the 1000 data.)

说明：  介绍使用matlab对ofdm进行编程，掌握其基本原理(Introduction to program using matlab on ofdm and grasp the basic principles)

信号的预处理，去除趋势项，以达到我们所要的信号的形式，效果比较好(Signal pre-processing to remove the trend term, we want to achieve in the form of signals, results were better)
