How to get the null space of large sparse matrix using Block-Wiedemann??

[권다운]

I have a very large sparse rectangular matrix ( about 4,000 x 200,000 ).

I want to get null space of this matrix by using Block-Wiedemann.

But I'm new in Linbox and programming. So, I don't know how to use the Block-Wiedemann in Linbox.

Please let me know how to use Block-Wiedemann in Linbox.

See omp-block-rank.C in examples/.
