说明：  matlab功能宝典，绝对经典,里面有十八个压缩文件，好好使用(A book about Matlab)

帮助您了解遗传算法实例及如火如何通过matlab 实现编程(Examples to help you understand and genetic algorithm matlab realize how fiery programming)

使用MATLAB生成线性调频信号，并进行傅里叶变换，并进行脉冲压缩(Chirp signal is generated using MATLAB and Fourier transform, and pulse compression)

function g=nonlineareq(x) Here is an example of nonlinear system that can be solved by using the Matlab command "fsolve" written in the file called "solution.m" (see quasi-Newton or Levenberg-Marquardt methods). g(1)=x(1)-4*x(1)*x(1)-x(1)*x(2) g(2)=2*x(2)-x(2)*x(2)+3*x(1)*x(2)

一些非常有用的遗传算法函数，可以和大家一起分享学习一下。(Some very useful genetic algorithm function, you can learn about and share with everyone.)

Matlab中提供了一种快速实现多项式拟合的方法函数polyfit()函数， 其格式：p=polyfit(x,y,n)其中x，y为样本向量，n为拟合的多项式的项数。下面拟f(x)=sinx+x,在区间【-3,3】上以0.5为间隔进行拟合。(Matlab provides a fast way to achieve polynomial fitting function polyfit () function, The format: p = polyfit (x, y, n) where x, y as the sample vector, n is the number of items of polynomial fitting. The following proposed f (x) = sinx+ x, the interval-3,3】 【intervals on the order of 0.5 to fit.)
