Dear all, Let's assume we are given an integer matrix like
m := [ [ 1, 0, 0 ], [ 0, -1, 0 ], [ 0, 0, 1 ] ] How do we compute all eigenvalues of m with multiplicities? If I use the command Eigenvalues(Rationals, m); I only get as output [1,-1] but actually need something like [1,1,-1]. I browsed GAP's manual but didn't find anything. Thanks in advance.
