chap10_3

this is matlab code for fourier transform and window function comparision

to solve the ordinary differential equation given as x^2 u - 2x u - 4u = x^2, 10 < x < 20 u(10) = 0 and u(20) = 100 using 10 linear elements

说明：  这是很有用的模式分类原代码，值得借鉴！推荐下载！(This is a very useful pattern classification original code, is worth learning! Recommended download!)
