This one is complicated than the former . by using sparsity matrix technique and recursion , it can also be used in the larger system . the simulation system is constituted with matlab and the programs are formed with c language 前者算法結(jié)構(gòu)簡(jiǎn)單,便于編程實(shí)現(xiàn),且計(jì)算速度快,主要適用于規(guī)模較小的系統(tǒng);后者算法結(jié)構(gòu)較前者復(fù)雜,程序?qū)崿F(xiàn)困難,但由于采用了稀疏矩陣技術(shù),并用遞推法修正因子表,所以可以應(yīng)用于規(guī)模較大的系統(tǒng)。
