Eigenvalues : eigenvals

eigenvals takes as argument a square matrix A of size n.
eigenvals returns the sequence of the n eigenvalues of A.
Remark : If A is exact, Xcas may not be able to find the exact roots of the characteristic polynomial, eigenvals will return approximate eigenvalues of A if the coefficients are numeric or a subset of the eigenvalues if the coefficients are symbolic.
