Re: Good eigenvalue/eigenvector test problems for eigs?

[Sebastien Loisel]

This was my thinking as well, the the problem should be easy. By try the
code I supplied under matlab and see what you get for "det(A - lamba *
eye(n))".

for k=1:n foo(k)=det(B-ei(k)*eye(n)); end;
plot(foo);

for the complex matrices shows that the det is <= 10^-20.
