Comment(by lftabera):
- I have added more documentation and doctest.[[BR]]
- The variable argument is now optional in both univariate and
multivariate. If it is not used, the first variable of the polynomial ring
is used.[[BR]]
- I have added coercion to be able to compute the Sylvester matrix of
polynomials in different rings, for ex. ZZ[x] and QQ[x] [[BR]]
- solved an issue for the dimension of the matrix of the sylvester matrix
of (x**n, 0)
It is not ready for review because the sylvester matrix of (0,0) is not
implemented.
