麻烦哪位大侠用MATLAB帮我计算一下这个方程吧~
0.2043A-1.6419B+0.05427C+0.04517D=0
33.5184A+36.153B-0.00002847C-0.000778D=0
-1.1572A-0.9833B-0.0802C+0.001044D=0
47.2565A-O.4125B+0.00057284C+0.0005759D=0
0.2043A-1.6419B+0.05427C+0.04517D=0
33.5184A+36.153B-0.00002847C-0.000778D=0
-1.1572A-0.9833B-0.0802C+0.001044D=0
47.2565A-O.4125B+0.00057284C+0.0005759D=0
这个是个齐次方程，因此，如果行列式不为零，那么其解为A=B=C=D=0；
A=[0.2043,-1.6419,+0.05427,+0.04517;
33.5184,+36.153,-0.00002847,-0.000778;
-1.1572,-0.9833,-0.0802,+0.001044;
47.2565,-0.4125,+0.00057284,+0.0005759]
b=[0;0;0;0];
A\b
[A B C D]=solve('0.2043*A-.6419*B+0.05427*C+0.04517*D=0','33.5184*A+36.153*B-.00002847*C-.000778*D=0','-.1572*A-.9833*B-.0802*C+0.001044*D=0','47.2565*A-.4125*B+0.00057284*C+0.0005759*D=0')
A =
0.
B =
0.
C =
0.
D =
0.
