Zi = INTERPTRI(TRI,X,Y,Z,Xi,Yi) linearly interpolates the scattered data in vectors X,Y,Z as described by the triangulation TRI as returned by DELAUNAY at the individual pairs of points in Xi and Yi. That is, Zi(k) is the linear interpolation at the point (Xi(k),Yi(k)). Xi and Yi are not MESHGRIDed as they are in GRIDDATA when Xi is a row vector and and Yi is a column vector.
