Hi,

I can't get the following snipped from the doc examples to work:

#include <iostream>
#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/io.hpp>

int main () {

    using namespace boost::numeric::ublas;

    vector<double> v1 (3), v2 (3);

    for (int i = 0; i < std::min (v1.size (), v2.size ()); ++ i)

        v1 (i) = v2 (i) = i;

    std::cout << outer_prod (v1, v2) << std::endl;

}

ublas_cross.cc: In function `int main()':
ublas_cross.cc:17: `outer_prod' undeclared (first use this function)
ublas_cross.cc:17: (Each undeclared identifier is reported only once for
each function it appears in.)

What's wrong here?

Thanks
Olaf
