Hi list, I'm not sure about the behavior of the hermite_form() function of an integer matrix. As far as I know the Hermeiteform H of a given matrix A, it is a unique (up to reordering of the rows and columns) triangular matrix (with some extra conditions) wich could be obtained by A * U = H for some U \in GL(\Z). (compare e.g. wikipedia) But the sagewiki says the following: H, U = A.hermite_form(transformation=True, include_zero_rows=False) U*A == H >>True which violates the given definition above, because the multiplication is from the left here) In my case it's important if H is optained by row operations or by columnoperations. How is this handled in sage, and is this somehow controlable?
