Hello,

I have a very large matrix and must extract disjoint sets randomly.  
The size is NxM and I need only the rows of the matrix (N). Is there  
any boost functionality for this? My solution should be: create a  
vector with index numbers [0..N) and swap the number random and use  
this vector with a slice for extracting the rows.

Thanks

Phil
