Evaluation of the expression type of a transpose sparse vector/sparse vector multiplication.Via this type trait it is possible to evaluate the resulting expression type of a transpose sparse vector/sparse vector multiplication (inner product). Given the transpose sparse vector type VT1 and the non-transpose sparse vector type VT2, the nested type Type corresponds to the resulting expression type. In case either VT1 is not a transpose sparse vector type or VT2 is not a non-transpose sparse vector type, the resulting Type is set to INVALID_TYPE.
