I am using maple 13 to found Eingenvalues of an hermitian matrix :
my surprise is that maple gives me 8 correct solutions an 2 complex eigenvalues which are not acceptable (we now that the eigenvalues for an hermitian matrix are all real) .
To understand the output of maple, first, I suspect that the complex part of the roots was null but without success I haven't found how to do it zero...
is it a bug? Thanks a lot to cooperation
