这是一个matlab版的基础响应分析功能文件，非常有用。(This is a matlab version of the document based on the functional response analysis, very useful.)

电磁场的时域有限差分法的matlab模拟的程序，计算电磁学的大牛写的程序。(the program writed by famous professor simulates electromagnetic field with FDTD)

code for filtering for DWT Chain process

Geometrical nonlinear finite element solver

使用matlab来实现数据的频谱分析，excel数据可以使用随机数据。(Using Matlab to realize signal spectrum analysis, excel can use random data.)

Vertical Handoff Algorithm

本程序实现了一维稳态无源项的对流-扩散方程的数值解法，采用的离散格式包括中心差分，一阶迎风，混合格式与QUICK格式。并画出其与精确解的比较。(This program implements a one-dimensional steady-state convection passive items- diffusion equations numerical solution, a discrete format used include center differential, the first order upwind, mixed format QUICK format. And draw the comparison with the exact solution.)

求解抛物型方程的交替隐方向P-R差分格式的matlab程序实现。不过大家在用的时候要用到原函数f.m和精确解函数uexact.m，应用程序的时候只要修改精确解和右端项就可以了。(Solving Parabolic Equations PR alternating direction implicit difference scheme of matlab program. But we can use the time to use the original function fm and the exact solution function uexact.m, whenever an application to amend the exact solution and the right side of it.)
