Description
A.<Y> = QQ[] R.<X> = LaurentPolynomialRing(A) matrix(R,2,2,[X,0,0,1])
gives a
TypeError: Unable to coerce X (<type 'sage.rings.polynomial.laurent_polynomial.LaurentPolynomial_mpair'>) to Rational
The same problem occurs with LaurentSeriesRing
, but not with PowerSeriesRing
.
I have not tried to chase where the problem actually comes from.
