TRIANGULATION_PLOT is a MATLAB program 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 program which displays a basis function associated with a linear triangle ("T3") mesh.
FEM_BASIS_T6_DISPLAY, a MATLAB program which reads a quadratic triangle mesh and displays any associated basis function.
TABLE_DELAUNAY, a FORTRAN90 program which can construct the triangulation data for a given node file.
TRI_SURFACE_DISPLAY, a MATLAB program which reads data defining a triangular mesh of a 3D surface and displays it.
TRIANGULATION, a MATLAB library which is useful for working with triangulations.
TRIANGULATION_CORNER, a MATLAB program which patches triangulations so that no triangle has two sides on the boundary.
TRIANGULATION_DELAUNAY_DISCREPANCY, a MATLAB program which measures the amount by which a triangulation fails the local Delaunay test;
TRIANGULATION_DISPLAY, a MATLAB program which displays the nodes and elements of a triangulation on the MATLAB graphics screen;
TRIANGULATION_DISPLAY_OPENGL, a C++ program which reads files defining a triangulation and displays an image using Open GL.
TRIANGULATION_HISTOGRAM, a MATLAB program which computes histograms of data over a triangulation.
TRIANGULATION_MASK, a MATLAB program 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 program 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 program which estimates the integral of a function over a triangulated region.
TRIANGULATION_REFINE, a MATLAB program which reads data defining a triangulation, replaces each triangle by four congruent smaller ones, and writes the new triangulation information to a file.
TRIANGULATION_TRIANGLE_NEIGHBORS, a MATLAB program which reads data defining a triangulation, determines the neighboring triangles of each triangle, and writes that information to a file.
ELBOW3 is an elbow-shaped region, triangulated using order 3 triangles.
ELL3 is an order 3 triangulation of a set of nodes in an L-shaped region.
ELL6 is an order 6 triangulation of a set of nodes in an L-shaped region.
HEX_HOLES3 puts a set of nodes into the double hexagonal hole region using CVT techniques, and creates an order 3 triangulation using TABLE_DELAUNAY.
LAKE3 uses constrained CVT methods to place nodes inside and on the boundary of the problem 14 triangulation region, a lake with an island. An order 3 triangulation is used.
