Description

There is an operator+( FieldVector< K, SIZE >, FieldVector< K, SIZE > ). Is there any reason that operator*( K, FieldVector< K, SIZE > ) and its variants are not implemented?

If there is none, I suggest to add the following code to fvector.hh, if expression templates are not available:

  template< class K, int SIZE >
  FieldVector< K, SIZE > operator* ( const K &k, const FieldVector< K, SIZE > &v )
  {
    FieldVector< K, SIZE > w( v );
    return w *= k;
  }

  template< class K, int SIZE >
  FieldVector< K, SIZE > operator* ( const FieldVector< K, SIZE > &v, const K &k )
  {
    FieldVector< K, SIZE > w( v );
    return w *= k;
  }

  template< class K, int SIZE >
  FieldVector< K, SIZE > operator/ ( const FieldVector< K, SIZE > &v, const K &k )
  {
    FieldVector< K, SIZE > w( v );
    return w /= k;
  }
