[ublas] add value to each element in a vector

Hi,

I'm using the vector and matrix classes in Boost to convert some
Matlab code to C++. I'm having troubles with this code:

typedef boost::numeric::ublas::vector<double> Vector_t;
Vector_t a(3);
a(0) = 0; a(1)=1; a(2)=2;

Vector_t b = a * 0.5; //works
Vector_t c = a + 0.5; //compiler error

error C2678: binary '+' : no operator found which takes a left-hand
operand of type 'Vector_t' (or there is no acceptable conversion)

How can I solve this? How can I add a constant value to each element
in a vector?

bye, Johan.
