DFT

Generate a 3D point plot of L=(x,y,z) using the values in the vector c to determine the color of each point. If c is empty, then z (column 3 of L) is used to color the plot. The data points are sorted so that plot3 is only called once for each group of points that map to the same color. The upper and lower limits of the color range (and the z axis) can be defined with crange. This is useful for creating a series of plots with the same coloring. The colormap (but not the colorbar) is flipped upside down if crange is given as [max min] instead of [min max]. The figure handle is returned if an output argument is given.

This is a MATLAB code for calculating effective index in PCF by using maxwell s equation and bessels function.

The Hurst parameter H characterizes the degree of long-range dependence (and asymptotic selfsimilarity) in stationary time series. Many methods have been developed for the estimation of H data. In practice, however, the classical estimation techniques can be severely affected by nonstationary artifacts in the time series.

Euler方法求解微分方程的源程序，很实用，绝对正确，还有画图功能，图形中描出点来，简单易懂。(Euler method for solving differential equations of the source, very practical, absolutely right, there are drawing function, points to delineate the graphic, easy to understand.)

在这个实验中，需要输入一个整周期内100个采样点的值，没有利用查找表的方法实现，而是直接在程序中输入100个采样点的值。2FSK/2PSK主要包括两部分2FSK信号发生器和2PSK信号发生器。2FSK信号发生器主要有分频器，m序列产生器，跳变检测，正弦信号发生器和DAC几个部分组成。2FSK的关键是通过判断信号跳变是来改变频率的变化，2PSK的关键是通过信号的跳变来改变相位的变化。(psk)
