Abstract: In this paper we have found out the end vertex adjacency matrix and end vertex incidence matrix on Dutchwind mill graphs. We have also found out the rank of the end vertex adjacency matrix and finalized the bounds for the e-chromatic number of some Dutchwind mill graph.

Keywords: end vertex adjacency matrix, end vertex incidence matrix, dutchwind mill graph, e-spectrum, e-chromatic number, e-eigen value
