ddot()

template<typename ExprL , typename ExprR >

auto Feel::vf::ddot	(	ExprL	l,
		ExprR	r
	)		-> decltype( trace( trans( l ) * r ) )

double dot product of the left and right expressions

Note

it handles matricial(rank 2 tensors) expressions

Returns

the double dot product \((l : r)\)

outer_prod()

template<typename ExprL , typename ExprR >

auto Feel::vf::outer_prod	(	ExprL	l,
		ExprR	r
	)		-> decltype( l * trans( r ) )

inner product of the left and right expressions

Note

it handles vectorial expressions

Returns

the inner product \((l * r^T)\)
