quadrilateral_mesh_order1_display

quadrilateral_mesh_order1_display, an Octave code which plots piecewise constant data defined on a quadrilateral mesh.

The input from the user includes:

• NODE_XY(1:2,1:NODE_NUM), a list of the coordinates of nodes;
• ELEMENT_NODE(1:4,1:ELEMENT_NUM), a list of the nodes that make up each element in the mesh;
• VALUE(1:TRIANGLE_NUM), the value associated with each element;

Usage:

quadrilateral_mesh_order1_display ( 'prefix' )

• 'prefix'_nodes.txt, lists the node coordinates;
• 'prefix'_elements.txt lists the indices of nodes that form elements.
• 'prefix'_values.txt lists the value to be assigned each element.
