代码说明:

OMP算法属于贪婪迭代算法,是压缩感知重构算法中最基本的算法,选择与原始信号相关性最大的原子来实现对信号的重构,ROMP算法在其基础上,通过引入正则化因子,进一步严格了筛选原子的条件,CoSaMP算法则每次迭代时,通过选择2倍稀疏度的原子来重构原始信号。

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • enigma
    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
