MESH_DISPLAY
Plot a Polygonal Mesh

MESH_DISPLAY, a MATLAB program which plots the nodes and elements of a polygonal mesh, with optional numbering.

MESH_DISPLAY reads two files describing the node coordinates and the elements of a polygonal mesh, and plots them.

Usage:

mesh_display ( 'prefix', node_vis, element_vis )

where 'prefix' is the common prefix for the node and element files:

'prefix'_nodes.txt, the node coordinates.
'prefix'_elements.txt, the element file

and node_vis is an integer defining the node visibility:

0, do not show the nodes;
1, show the nodes;
2, show the nodes and label them.

and element_vis is an integer defining the element visibility:

0, do not show the element;
1, show the element;
2, show the element and color them.
3, show the element and color them, and label them.
