TRICONTOUR Triangular Contour Plot.

TRICONTOUR(TRI,X,Y,Z,N) draws scalar N contour lines treating the values

in Z as heights above a plane. TRI,X,Y,and Z define a triangulation where

the triangles are defined by the M-by-3 face matrix TRI, such as that

returned by DELAUNAY. Each row of TRI contains indices into the X,Y, and

Z vertex vectors to define a single triangular face. Contours are

computed directly from the triangulation rather than interpolating back

to a cartesian grid using GRIDDATA.

TRICONTOUR(TRI,X,Y,Z,V) draws length(V) contour lines at the values

specified in vector V.

TRICONTOUR(TRI,X,Y,Z,[v v]) draws a single contour line at the level v.- TRICONTOUR Triangular Contour Plot.
