Name
tripcolor — Pseudo color 2-D plot based on a triangulation
Calling Sequence
hdl = tripcolor(TRI,X,Y,C)
Parameter
- TRI
3 by n matrix
- X
1 by n matrix
- Y
1 by n matrix
- C
n by n matrix
- hdl
Handle of the created Fac3d entity
Description
tripcolor(TRI,X,Y,C) displays the triangles defined in the 3-by-M face matrix TRI as pseudocolor patches. A row of TRI contains indexes into the X,Y vertex vectors to define a single triangular face. The color is defined by the vector C.
tripcolor(...,'param','value','param','value'...) allows additional param/value pairs to be used. See pcolor for the possible param/value pairs.
