I think coefficients_monomials() is the most descriptive, as it tells you what you get back and in what order. C, m = PS.coefficients_monomials() assert PolynomialSequence(C*m) == PS (incidentally, the assert also holds true with the return values of coefficient_matrix) Also, thinking about whether C should be transposed: I think it's logical that the rows of C are the coefficients of members of the sequence (since matrices are closest to sequences of rows in sage), so C is already correct in that sense. Therefore, m should indeed be a "column" vector, but sage is ambivalent about whether vectors are rows or columns and therefore we can safely return it as a vector. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
