maple中矩阵特征值为负用什么命令开出虚数来呢?
在maple里带有字母的矩阵特征值如果根号下面是多项式,此多项式是负的,用什么命令开出虚数来呢?谢谢各位大侠。如矩阵为A:=matrix(8,8,[-a1*bI,0,0,0,1,0,0,0,0,-a1*bI,0,0,0,1,0,0,0,0,-a1*bI,0,0,0,1,0,0,0,0,-a1*bI,0,0,0,1,-a^2,a^2,0,0,0,-a1*bI,0,0,a^2/b,-(r+1)*a^2/b,r*a^2/b,0,0,-a1*bI,0,0,0,r*a^2/b,-r*a^2/b,0,0,0,-a1*bI,0,0,0,r*a^2*tanc/b,-r*a^2/b,0,0,0,-a1*bI]);其中r>0,b>0,-2*b*(-(4*r^2-4*r*b+1+2*b+b^2)^(1/2)+2*r+1+b)<0,
T:=charpoly(A,x);T为特征多项式。
N:=eigenvalues(A);N为特征值。怎么解出特征值为虚数的六个解。
用什么命令表示-2*b*(-(4*r^2-4*r*b+1+2*b+b^2)^(1/2)+2*r+1+b)<0,
谢谢。 这个问题最好去,工程数学软件问问
