triplot - 2-D triangular plot

Syntax

Description

triplot(TRI,x,y) displays the triangles defined in the m-by-3 matrix TRI. A row of TRI contains indices into the vectors x and y that define a single triangle. The default line color is blue.

triplot(TRI,x,y,color) uses the string color as the line color. color can also be a line specification. See ColorSpec for a list of valid color strings. See LineSpec for information about line specifications.

h = triplot(...) returns a vector of handles to the displayed triangles.

triplot(...,'param','value','param','value'...) allows additional line property name/property value pairs to be used when creating the plot. See Line Properties for information about the available properties.

Examples

Plot a Delaunay triangulation for 10 randomly generated points.

X = rand(10,2);
dt = DelaunayTri(X);
triplot(dt)

Plot the Delaunay triangulation in face-vertex format.

tri = dt(:,:);
triplot(tri, X(:,1), X(:,2));
