Files included:
- graphbrowser.mlapp - a browser app for the numerous examples in graphgallery.m
- graphcolouring.m - a function to determine a minimal vertex colouring of a graph
- graphgallery.m - a function providing numerous example graphs
- graphgirth.m - a function calculating the girth of a graph
- graphinfo.m - a class for holding information about a graph
- graphradiusdiameter.m - a function calculating the radius and diameter of a graph
- randgraph.m - a function to generate a random graph with n vertices and probability p of each edge
graphbrowser and graphcolouring both require the Optimization Toolbox, however for graphbrowser it's only if you press the "Colour vertices" button.
Use of the browser app is straight forward and the functions have extensive documentation.
