Publisher review:INTERPTRI Interpolate Triangulation - Linearly interpolate scattered triangulated data. 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. Use MESHGRID when desired. For example,[Xii,Yii] = MESHGRID(Xi,Yi);Zi = INTERPTRI(TRI,x,y,z,Xii,Yii);is the same asZi = GRIDDATA(x,y,z,Xi(:).',Yi(:));INTERPTRI is faster than GRIDDATA when the same data is interpolated more than once because the triangulation TRI is precomputed and passed into INTERPTRI, whereas it is computed within GRIDDATA each time it is called.
