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

these matlab files are different modulation techniques in communication

matlab codes to solve single variable unconstrained optimization problem using five methods

本文件包含了两个直扩和跳频的例子，用MATLAB语言实现，而且还包括例子的原文及大量注释，十分详细(This document contains two examples of DS and FH, with the MATLAB language, but also examples of the original and a lot of notes, very detailed)

说明：  最小外接矩形，根据面积和周长判断。实现图象处理的工程计算。( Compute the minimal bounding rectangle of points in the plane usage: [rectx,recty,area,perimeter] = minboundrect(x,y,metric) arguments: (input) x,y- vectors of points, describing points in the plane as (x,y) pairs. x and y must be the same lengths. metric- (OPTIONAL)- single letter character flag which denotes the use of minimal area or perimeter as the metric to be minimized. metric may be either a or p , capitalization is ignored. Any other contraction of area or perimeter is also accepted. DEFAULT: a ( area ) )
