The files included implement the M3 Enigma machine. Rotors.m implements the GUI and enigma.m implements the cipher substitutions. The implementation can be used as an aid to teaching the enigma machine. Also, the source can be used to show how to implement an enigma machine. The files are thoroughly commented and the application can run in MATLAB by just typing rotors

说明：  谐波小波波程序，包括几个例子，让大家可以对谐波小波处理信号有更加透彻深入的理解和认识。。。(Small wave harmonic procedures, including a few examples, so that we can handle signals of harmonic wavelet a more thorough understanding of and awareness. . .)

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出。以第1边界条件为例，用节点处二阶导数表示三次样条插值函数，用追赶法求解相关方程组。(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. In the first boundary condition, for example, with a node represents the second derivative of the cubic spline interpolation function, solving equations associated with the catch method.)

利用单带滤波器来设计一个半带滤波器，并显示半带滤波器H0,H1,及 H0+H1的幅频响应 单带滤波器的归一化截止频率为0.84,长度＝16，半带滤波器的长度＝31。(to explain how to design a biorthogonal FB by Lattice structure)
