gplot(A,xy) plots the graph specified by A and xy. A graph, G, is a set of nodes numbered from 1 to n, and a set of connections, or edges, between them. In order to plot G, two matrices are needed. The adjacency matrix, A, has A(i,j) nonzero if node j. The coordinates array, xy, is an n-by-2 matrix with the position for node i in the i-th row, xy(i,:) = [x(i) y(i)].
gplot(A,xy,lc) uses a specified line type and color instead of the default, solid red lines. See plot for a description of valid line types.
