Hey Everyone!

I cant figure out why Maple can give eigenvectors for a matrix A, through Eigenvectors(A); but I cant use LinearSolve() to do this same calculation. (I get <0.,0.> as the answer).

Here is what I am doing (note, Eigenvectors(S) gives correct answer).

with(LinearAlgebra);

S:=<<7476.45,303.62>|<303.62,26.19>>;

I2:=IdentityMatrix(2);
charPoly:=Determinant(x * I2 - S);
EV:=solve(charPoly=0,x);

         produces: EV := 7488.802926, 13.83707411
