DIST_PLOT is available in a MATLAB version.
DISTMESH, a MATLAB program which is Strang and Persson's code for generating meshes over regions with an associated distance function.
LEVELS, a MATLAB library which makes a contour plot, choosing the contour levels using random sampling.
TABLE_IO, a MATLAB library which reads and writes files using the TABLE format; these routines are used by DIST_PLOT_DEMO when reading the input files.
TEST_TRIANGULATION, a MATLAB library which defines some test regions for triangulation.
TRIANGULATION_ORDER3, a data directory which discusses order 3 triangulations; The node and triangle files input to DIST_PLOT are an example of such triangulations.
TRIANGULATION_PLOT, a MATLAB program which can make a plot of a triangulation.
TRIANGLE, a C program which can triangulate a region.
DIST_PLOT_DEMO displays plots for all the standard problems used in DISTMESH:
P01 is the circle:
P02 is the circle with a hole:
P03 is the square with a hole:
P04 is the hexagon with hexagonal hole:
P05 is the horn:
P06 is the superellipse:
P07 is the bicycle seat:
P08 is the holey pie slice:
P09 is Jeff Borggaard's square with two hexagonal holes:
P10 is the unit square:
P11 is the L-shaped region:
P12 is the John Shadid's H-shaped region:
P13 is the Sandia fork:
P14 is Marcus Garvie's Lake Alpha, with Beta Island:
P15 is Sangbum Kim's forward step region:
P16 is Kevin Pond's elbow:
P17 is the channel with a Reuleaux triangle obstruction:
P18 is the dumbbell region:
