But such a constructor does not exist. I thought that using a

Can someone help me understand how I can do this (or some workaround)?

I don't know the answer, but it might be useful to know why you want to do that. I recall reading that the ublas::vector needs to remain a fixed size for its lifetime, so you have to be careful not to do anything to its storage to break its assumptions.

Yes, of course. I would like to be able to use std::vectors and ublas vectors (almost) interchangeably. I was hoping that if a function returned a std::vector and the calling function assigned that to a ublas vector then all would work out without any trouble. Is this not a possibility?

Thanks,
