I would like to ask if it is possible to get the lower triangular matrix from the factorization, or its parts are distributed among the processes.

"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 ...

Abstract: This paper mainly studies the fault estimation for a class of interconnected systems with simultaneous dynamic uncertainties and actuator faults. A lower triangular matrix based linear ...
