How to implement equivalent of magma NullSpace in Pari/GP

[Kevin Acres <research@research-systems.com>]

Hi,

I'm trying to implement an equivalent of the Magma NullSpace() function.

For example I'd like:

[0 0 0 1 0 0 1 0]
[1 0 1 0 0 0 1 0]
[1 1 0 0 0 0 0 1]
[0 1 1 0 0 0 0 1]
[0 1 1 0 0 0 0 0]
[0 0 1 0 0 1 0 0]

to return

[0 1 0 0 0 0 0 0 1]
[0 0 1 0 0 1 1 0 0]

I'm sure that it must be pretty trivial. It's just that I haven't 
worked out how as yet.

Any pointers in the right direction would be greatly appreciated.


Kevin.
