Add fill edge a gt b if there is a path from a to b through lowernumbered vertices But this doesn t work with numerical pivoting 1 2 3 4 7 6 5 A G A LU Nonsymmetric Gaussian elimination. Such matrices has several attractive properties they support algorithms with low computational complexity and make it easy to perform in cremental updates to signals We discuss applications to several areas including compressive sensing data stream Volkan .
