Hi,

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

#include <iostream> #include #include

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?

Just add #include The outer_prod is in matrix_expression.hpp which gets included by matrix.hpp. toon
