[ublas] vector to diagonal matrix

Hi,

what is the best way to construct a diagonal matrix from a vector (where the 
vector should be the diagonal).

I think I can use banded_matrix<> for diagonal matrices, but there seems to be 
no explicit constructors except for maybe assigning the vector to a slice of the 
banded_matrix<>? In this case, what are the performance implications?

Any help appreciated.
