Okay. I would start by implementing finite fields. Then I would create (extend?( classes of vector spaces and matrix spaces over finite fields. Next, I would implement (or extend?) the row-reduced echelon form algorithm to matrices over finite fields (it may exist in SymPy already over the reals or rationals or something like that).. Then I would basically steal "my" code for the Python class LinearCodes in Sage (see the previous email for the directory location). This would be a really good start I think. > > On Sat, Jan 30, 2010 at 1:25 AM, David Joyner <[email protected]> wrote: >> >> On Fri, Jan 29, 2010 at 5:17 PM, Kasun Samarasinghe >> <[email protected]> wrote: >> > david, >> > >> > I m looking out and reading several ideas these days.
