mklsgridtrinodeid2row.......convert node ID list into array row indices call: trilist=mklsgridtrinodeid2row(layer); layer: (struct) layer structure as returned by MKLSGRIDNEWTRILAYER result: trilist: triangle list with entries pointing to array rows of the .nodes field of LAYERS. This triangle list is analoguous to that needed e.g. by trimesh(). Use this list to plot the triangles via trimesh or trisurf. Martin Knapmeyer, 13.09.2004
