三个MATLAB里实现傅里叶变换FFT的源程序代码，每种代码都进行了作图演示(Three in MATLAB source code to achieve Fourier Transform (FFT), each code have been mapped demo)

改进的GM（1，1）程序，可实现时间序列的灰色等维新息预测，采用弃旧纳新的原则。(The improved GM (1, 1) program, can realize the time series prediction using grey information renewal, discarding the old and new principles.)

1. 牛顿迭代法 function [x,i]=newtonmethod(x0,f,ep,Nmax) 牛顿法求非线性方程根 x0是输入初始值, f是输入函数, 精度要求ep, Nmax为最大迭代次数 x是输出迭代序列,i是迭代次数 2. 二分法 function [x,k]=bisection(a,b,f,ep) 二分法解非线性方程 输入区间[a,b],函数f和误差ep, Nmax为最大二分次数 x为输出近似根, k为二分次数 ( Newton s law and the dichotomy)
