*The matrix library used for Z/p-matrices does not return the transformation matrix, so the transformation option is ignored.*
More specifically, the call:
> M.echelon_form(transformation=True)
returns only the echelon matrix E but not the transformation matrix T, so that T*M=E, when M is over a finite field.
Is there any workaround? Can I get the transformation matrix over QQ and then reduce it over the finite field?
Any advice is much appreciated.
Thanks,
