MATLAB 计算方程
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

Answer 1

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
