We can scale an operator on a rational algebra by a rational number::
sage: J = RealSymmetricEJA(2)
- sage: e0,e1,e2 = J.gens()
- sage: x = 2*e0 + 4*e1 + 16*e2
+ sage: b0,b1,b2 = J.gens()
+ sage: x = 2*b0 + 4*b1 + 16*b2
sage: x.operator()
Linear operator between finite-dimensional Euclidean Jordan algebras
represented by the matrix:
