Dear all,

would it be possible to introduce an example "nullspace.C"
in the "examples" directory of linbox?

I am interested in using linbox for finding the rational kernel of 
integral matrices. There is already some "test-nullspace.C" in
the tests directory.

I think this would be a natural way to use linbox for.

Dear Mathieu,
there is already an example in linbox/examples/nullspacebasis.C, over a finite
field.
To make it work over the rationals, just change the field to
Givaro::QField<Givaro::Rational>.
Regards,
