I want to get the transformation matrix from the echelon form reduction over finite fields but I found in the SageMath documentation the following statement:
*The matrix library used for Z/pZ/p-matrices does not return the transformation matrix, so the transformation option is ignored* Link: http://doc.sagemath.org/html/en/reference/matrices/sage/matrix/matrix2.html#sage.matrix.matrix2.Matrix.echelon_form More specifically, the call: *M.echelon_form(transformation=True**) *does not return the transformation matrix T when M is over a finite field, only the echelon matrix E; T is such that we have T*M=E, so T is just the product of the elementary matrices, which perform the reducing row operations. Is there any workaround to get the transformation matrix T over a finite field? Can I get the transformation matrix T over ZZ and then reduce it over the finite field? Any advice would be much appreciated. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
