一个线阵的数字多波束形成matlab程序(A linear array, digital beamforming matlab program)

利用Matlab软件工具，对简单的植被形态进行模拟，模拟结果生动逼真。首先，迭代产生一系列字符串；其次，根据将L系统与图形联系起来，采用龟形的概念赋予每个字符特定的图形含义；最后，读取字符并画图，根据读取到的字符通过Matlab实现相应的操作。(According to L system and iterated algorithm, shape of trees were simulated with matlab functions and programs and the fractal trees’ configurations were natural and living. First, we use iteration to produce a series of string. Then, connecting the L system with graphs, we use the theory of turtles to give each character a specific meaning. Finally, read the string and draw pictures with the matlab. )
