OFDM process with FFT submission

this code is for PCA function, used to reduce the dimension

frequency modulation code written in matlab

该程序是方向滤波器工具包，其中有很多现成的滤波器，及上下采样程序。可直接调用。(The program is the direction filter kit, there are many ready-made filter, and down sampling procedure. Can be called directly.)

本代码为割线法求解非线性方程组。其调用格式为[r,m]=mulGXF1(F,x0,x1,eps) 其中，F:非线性方程组；x0初始解；x1：初始解；eps：解的精度；m：迭代步数。(The code for the secant method for solving nonlinear equations. Its call format [r, m] = mulGXF1 (F, x0, x1, eps) where, F: non-linear equations x0 initial solution x1: initial solution eps: solution accuracy m: the number of iterative steps.)

这个是收集的一个用matlab编写的车牌定位的程序，很好用的！(This is a collection of using Matlab positioning plates prepared by the procedure is useful!)

旋转图形的Matlab的源代码，可以任意修改，且易读性强(Rotating graphics Matlab source code can be modified, and the legibility strong)

菲涅尔衍射积分的 S FFT算法。理解用S FFT算法完成菲涅尔积分原理，特别是确定观察面尺寸的原理及相应公式的来源。(The Fresnel diffraction integral S- FFT algorithm.Understand complete Fresnel integral principle with S- FFT algorithm, especially the observation surface size of the source of the principle and the corresponding formula.)

通过均值聚类实现四类数据的分类，一直在用(means clustering )
