Evaluation of the expression type of a transpose dense vector/scalar multiplication.Via this type trait it is possible to evaluate the resulting expression type of a transpose dense vector/scalar multiplication. Given the transpose dense vector type VT and the scalar type ST, the nested type Type corresponds to the resulting expression type. In case either VT is not a transpose dense vector type or ST is not a scalar type, the resulting Type is set to INVALID_TYPE.
