通过matlab变成来实现RD函数迭代算法，并绘制出RD函数图像-realise the algorithm of RD and draw the image of RD

这是matalab计算脉冲序列控制算法中迭代部分核心思想，通过这个计算能够有效地计算出分叉结果。-This is a matlab to calculate the pulse sequence control algorithm iterative part of the core ideology, by this calculation can effectively calculate the bifurcation results.
