fem2d_mesh_display, an Octave code which plots the nodes and elements of a mesh involved in the finite element method (FEM).
The code reads the FEM model of a mesh, that is, a file listing the node coordinates and a file listing the indices of the nodes that form each polygonal element. It displays the mesh, with optional number of nodes or elements.
fem2d_mesh_display ( 'prefix', node_vis, element_vis )where 'prefix' is the common prefix for the node and element files:

fem2d_mesh_display is available in a MATLAB version and an Octave version.
bezier_surface_display, an Octave code which displays a Bezier surface;
fem_basis_t3_display, an Octave code which displays a basis function associated with a linear triangle ("T3") mesh.
fem_basis_t6_display, an Octave code which reads a quadratic triangle mesh and displays any associated basis function.
fem2d_scalar_display, an Octave code which reads information about nodes, elements and nodal values for a 2D finite element method (FEM) and creates a surface plot of U(X,Y), using the MATLAB graphics system.
fem2d_scalar_display_gpl, an Octave code which reads information about nodes, elements and nodal values for a 2D finite element method (FEM) and creates a GPL file describing a surface plot of U(X,Y), which can be displayed by gnuplot.
fenics_to_fem, examples which illustrate how a mesh or scalar function computed by the FENICS program can be written to FEM files, which can then be used to create images, or as input to meshing programs or other analysis tools.
grid_display, an Octave code which can display a 2D or 3D grid or sparse grid.
gridlines, an Octave code which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.
polygonal_surface_display, an Octave code which displays a surface in 3D described as a set of polygons;
quad_surface_display, an Octave code which plots piecewise bilinear data associated with a QUAD_SURFACE, that is, a 3D surface defined by a quadrilateral mesh;
tet_mesh_display, an Octave code which reads in the node and tetra files defining a tet mesh and displays a wireframe image.
tri_surface_display, an Octave code which reads data defining a triangular mesh of a 3D surface and displays it.
triangulation_display, an Octave code which displays the nodes and elements of a triangulation on the MATLAB graphics screen;
triangulation_plot, an Octave code which plots a triangulation as a PostScript file.
