egvl (or eigenvalues eigVl) takes as argument a
square matrix A of size n.
egvl (or eigenvalues eigVl) returns the Jordan normal
form of A.
Remark : If A is exact, Xcas may not be able
to find the exact roots of the characteristic polynomial,
eigenvalues will return an approximate diagonalozation of A if the
coefficients are numeric.
