"This notebook walks you through how to implement $ x := L^T x $ where $ L $ is lower triangular. Vector $ y $ is not to be touched (and, indeed, not even passed into the routines). This is a little ...

"This notebook walks you through how to implement $ x := U x $ where $ U $ is upper triangular. Vector $ y $ is not to be touched (and, indeed, not even passed into the routines). This is a little ...

Abstract: Based on H 1 (curl) triangular interpolatory vector elements, explicit forms of the elemental matrices for the higher order vector elements are presented completely by using the classified ...
