Graceful labeling is one of the interesting topics in graph theory. Let G = ( V, E ) be a tree. The injective mapping is called graceful if the weight of edge are all different for every edge xy . The famous conjecture in this area is all trees are graceful. In this paper we give alternative construction of graceful labeling on symmetric tree using adjacency matrix.
