Graph GUI

create/edit graphs of vertices and edges

Description

Edit a graph or draw a new one with this GUI.

Usage:
>> graph_gui;
or
>> graph_gui(A,xy);
 
Controls:
Use the radio buttons to select an action:
1. To DRAW a new VERTEX, select 'Draw' and 'Vertex'. Then click inside the axes in the desired location.
2. To DELETE a VERTEX, select 'Delete' and 'Vertex'. Then click inside the axis near the desired vertex.
3. To DRAW an EDGE, select 'Draw' and 'Edge'. Then click and hold the mouse button down on the starting vertex and drag the mouse to the vertex of the desired connection.
 a. If 'Directed' is selected, a 1-way edge will be created from the first vertex to the second.
 b. If 'Undirected' is selected, a 2-way edge between the first vertex and the second vertex will be created.
 Note: If no vertices exist, no edges will be created.
4. To DELETE an EDGE, select 'Delete' and 'Edge'. Then click and hold the mouse button down on the starting vertex and drag the mouse to the vertex of the desired connection to delete.
 a. If 'Directed' is selected, only the 1-way edge between the first vertex and the second will be deleted.
 b. If 'Undirected' is selected, the entire 2-way edge between the first vertex and the second vertex will be deleted.
5. Click the 'Latch Points' checkbox to toggle between rounded and unrounded (x,y) points.
6. The number in the edit box specifies a rounding value. For example, a value of 0.5 rounds each (x,y) point to the nearest 0.5
7. Click the 'Save Graph' button to save the adjacency matrix (A) and the coordinates (xy) of the graph to a MAT file.
