HW_3

使用高斯列主元法和QR方法求解方程组，使用matlab编程.(Gaussian and QR column main element method for solving equations.)

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：  《现代通信系统使用MATLAB（第二版）》书中的例子打包。(communication systerm)

说明：  几种传统的图像插值放大方法：最近邻插值法，双线性插值法，双三次插值法(Several traditional interpolation to enlarge the image : nearest neighbor interpolation, bilinear interpolation, bicubic interpolation.)
