Hi Folks,
This is my first excursion into uBlas. I'm getting an "ambiguous
overload for 'operator*' in 'a * b' " sort of error out of this:
#include
#include
#include
namespace UB
{
using namespace boost::numeric::ublas;
template <int N> struct Type
{
typedef matrix > matrix;
};
}
// elsewhere...
typename UB::Type<N>::matrix a(N,N), b(N,N);
for (int i = 0; i < N; ++i)
for (int j = 0; j < N; ++j)
{
a(i,j) = 1.0 / (i + j+1);
b(i,j) = 1.0 / (i + j+1);
}
a * b;
The error (from GCC 3.4.6) is this ugly thing:
/usr/local/home/dgsteffen/local/GCC34/Boost/1_32/boost/numeric/ublas/matrix_expression.hpp:3632: note: candidates are: typename boost::numeric::ublas::matrix_binary_scalar2_traits, boost::numeric::ublas::scalar_reference<const T2> >::result_type boost::numeric::ublas::operator*(const boost::numeric::ublas::matrix_expression<E>&, const T2&) [with E1 = boost::numeric::ublas::matrix >, T2 = boost::numeric::ublas::matrix >]
/usr/local/home/dgsteffen/local/GCC34/Boost/1_32/boost/numeric/ublas/matrix_expression.hpp:3162: note: typename boost::numeric::ublas::matrix_binary_scalar1_traits, boost::numeric::ublas::scalar_reference<const T1> >::result_type boost::numeric::ublas::operator*(const T1&, const boost::numeric::ublas::matrix_expression<E2>&) [with T1 = boost::numeric::ublas::matrix >, E2 = boost::numeric::ublas::matrix >]
Any thoughts on what I'm doing wrong?
Thanks!
