function?[LUx]=chase（abcd）
%輸入格式如下，因為a是從第二行開始的，所以a1用0補，c截止到cn-1所以cn用0補，
%其實a1和cn-1都是不存在的，只為了程序中計算的對應問題。
%?a=（0a2a3……，an）;
%?b=（b1b2b3……bn）;
%?c=（c1c2……，cn-10）;
%?d=（d1d2……，dn）；
n=length（b）;
for?i=2:n
????a（i）=a（i）/b（i-1）;
????b（i）=b（i）-c（i-1）*a（i）;
????d（i）=d（i）-a（i）*d（i-1）;
end
d（n）=d（n）/b（n）;

????d（i）=（d（i）-c（i）*d（i+1））/b（i）;
