| Abstract: | Cylic double triangle is a digraph that contains two 3-cycles in structure.In this paper,the inverse M-matrix completion problems for the graph are studied in depth.The cases that every cycle contains all specified vertices and each cycle can contain unspecified vertices are all disussed.At the same time,the completion theorems and algorithm are given. |
