I wrote a simple program using uBLAS under vc 7.1, but
got so many warnings, how can I correct it?
The code is:
----------------------
#include
namespace ublas = boost::numeric::ublas;
int main(int argc, _TCHAR* argv[])
{
ublas::identity_matrix<double> A(4);
ublas::identity_matrix<double> B(4);
prod(A, B);
return 0;
}
------------------
But I got the following warning:
d:\Project\Libraries\boost_1_32_0\boost\numeric\ublas\traits.hpp(941)
: warning C4267: 'argument' : conversion from 'size_t'
to 'const unsigned int', possible loss of data

Linking...
How to correct it? thank you very much:)
