<title>Description</title>
<para>trisurf(TRI,X,Y,Z,C) displays the triangles defined in the 3-by-n
face matrix TRI as a surface. A row of TRI contains indexes into the X,Y,
and Z vertex vectors to define a single triangular face. The color is
defined by the vector C.</para>
<para>trisurf(TRI,X,Y,Z) uses C = Z, so color is proportional to surface
height.</para>
<para>trisurf(...,'param','value','param','value'...) allows additional
param/value pairs to be used. See mesh, surf, surfl for the possible
param/value pairs.</para>
