triangulation_plot, a MATLAB code which plots a triangulation.
TRIANGULATION_PLOT reads one file listing the nodes, and a second file consisting of groups of 3 or 6 nodes that make up triangles, and creates an Encapsulated PostScript image of the triangulation.
triangulation_plot ( 'prefix', node_vis, triangle_vis )where 'prefix' is the common prefix for the node and triangle files, and will also be used to name the output file:

triangulation_plot is available in a C++ version and a FORTRAN90 version and a MATLAB version.
fem_basis_t3_display, a MATLAB code which displays a basis function associated with a linear triangle ("t3") mesh.
fem_basis_t6_display, a MATLAB code which reads a quadratic triangle mesh and displays any associated basis function.
tri_surface_display, a MATLAB code which reads data defining a triangular mesh of a 3d surface and displays it.
triangulation, a MATLAB code which is useful for working with triangulations.
triangulation_corner, a MATLAB code which patches triangulations so that no triangle has two sides on the boundary.
triangulation_delaunay_discrepancy, a MATLAB code which measures the amount by which a triangulation fails the local delaunay test;
triangulation_display, a MATLAB code which displays the nodes and elements of a triangulation on the MATLAB graphics screen;
triangulation_histogram, a MATLAB code which computes histograms of data over a triangulation.
triangulation_mask, a MATLAB code which takes an existing triangulation and deletes triangles and their corresponding nodes as requested by the user.
triangulation_order3, a data directory which describes the node and triangle files used for an order 3 triangulation.
triangulation_order6, a data directory which describes the node and triangle files used for an order 6 triangulation.
triangulation_orient, a MATLAB code which reads data defining a triangulation, makes sure that every triangle has positive orientation, and if not, writes a corrected triangle file.
triangulation_quad, a MATLAB code which estimates the integral of a function over a triangulated region.
triangulation_refine, a MATLAB code which reads data defining a triangulation, replaces each triangle by four congruent smaller ones, and writes the new triangulation information to a file.
triangulation_svg, a MATLAB code which creates an svg image of a triangulation, which can be displayed by an web browser.
triangulation_triangle_neighbors, a MATLAB code which reads data defining a triangulation, determines the neighboring triangles of each triangle, and writes that information to a file.
