C++ API

: gplot (A, xy)

: gplot (A, xy, line_style)

: [x, y] = gplot (A, xy)

Plot a graph defined by A and xy in the graph theory sense.

A is the adjacency matrix of the array to be plotted and xy is an n-by-2 matrix containing the coordinates of the nodes of the graph.

The optional parameter line_style defines the output style for the plot. Called with no output arguments the graph is plotted directly. Otherwise, return the coordinates of the plot in x and y.
