SAR图像压缩感知 matlab代码 对应着汕大闫老师的那本压缩感知及其应用，有需要的可以看一下！！(SAR image compression matlab code that corresponds to the perception that this compressed sensing and its application Shantou Yan teacher in need can look at! !)

混合蛙跳算法程序，采用1、若干次运行取最优 2、增加进化代数maxgen 3、加大种群规模popsize。三种方法来可有效克服随机初始化带来的局部极小问题(Shuffled frog leaping algorithm, using one, several runs to take the best two, increasing evolution algebra maxgen 3, to increase the population size popsize. Three ways to effectively overcome local minima caused by random initialization problem)
