Hello,

I have n ublas vectors with different sizes. Now I would create a  
ublas matrix with n columns in that way, that each row has a  
combination of the vector elements. I need all combination of the  
vector elements (I know it is an exponential problem, but my vectors  
are small).

Do you have an idea how do I create the combinatoric matrix?

Thanks

Phil
