潮流计算和状态估计程序请教
潮流计算的：[PQ, PV, REF, NONE, BUS_I, BUS_TYPE, PD, QD, GS, BS, BUS_AREA, VM, ...VA, BASE_KV, ZONE, VMAX, VMIN, LAM_P, LAM_Q, MU_VMAX, MU_VMIN] = idx_bus;

上面这段程序什么意思啊？ 根据输入量个数不同，进而进行不同的操作！ 怎么还是matlab啊,我晕!!!!!!!!!!!!!!!!! 这段话是MATPOWER中的语句。前面几句是将三个输入的矩阵对每一列给定了一个INDEX，方便到时候引用。
后面nargin是根据输入变量的多少，进行不同的具体操作。 看了好几个星期的这样程序 还是看不懂啊 看不懂说的都是些什么。 默默打个酱油
