Example

In trans_mult.cc:

typedef matrix< double,
                rectangle<>, 
                dense<external>, 
                row_major >::type EMatrix;
typedef dense1D<double> Vector;
  const EMatrix::size_type n = 5;
  Vector y(n,1),Ay(n);
  double da[n*n];
  EMatrix A(da,n,n);
  mult(trans(A),y,Ay);
