[Boost-users] question about ublas

Hi folks!

I have two question:

 

1. In ublas::vector, there's 3 constructions:

vector ()
Allocates an uninitialized vector that holds zero elements.
vector (size_type size)
Allocates an uninitialized vector that holds size elements.
vector (const vector &v)

but how can i construct a vector with the default value like std::vector( n, value )

 

2. How to make ublas more efficiency?

I tried to comment some mac define of check in ublas/config.hpp, and found it make some sense.

I wonder if some one has  more experience to share.

 

Best regards!
