MATLAB不提供现成指数拟合函数，一方面由于但可以轻松通过多项式拟合转化而来，但是使用上还是不如有一个函数方便，所以特写这样一样简单实用的函数(MATLAB does not provide ready-exponential fit function, by hand because it can be easily transformed a polynomial fit, but still not as good as there is easy to use a function, it is as simple close-up of such useful functions)

用于解算一维非线性平流扩散方程的半隐式差分格式算法(Computing the numerical solution of nonlinear advection equation via a semi-implicit scheme. )

None Coding not anything to do

利用AF-BW filter及双线性变换法设计一DF，满足Wp=0.2p, Ws=0.6p, Ap£ 2dB, As³ 15dB (use AF-BW and bilinear transform filter design a DF, meet Wp = 0.2p, Ws = 0.6p, Ap)
