Write tile to field

Syntax

writeTile(gridID,fieldname,tileCoords,data)

Description

writeTile(gridID,fieldname,tileCoords,data) writes a single tile of data to a field. If the field data can be arranged tile by tile, this routine is more efficient than gd.writeField. In all other cases, use gd.writeField. The tileCoords argument has the form [rownum colnum] and is defined in terms of the tile coordinates, not the data elements.

This function corresponds to the GDwritetile function in the HDF-EOS library C API, but because MATLAB® uses FORTRAN-style ordering, the tileCoords parameter is reversed with respect to the C library API.

Examples

Define a field with a 2-by-3 tiling scheme.

import matlab.io.hdfeos.*
gfid = gd.open("myfile.hdf","create");
xdim = 200; ydim = 180;
gridID = gd.create(gfid,"PolarGrid",xdim,ydim,[],[]);
zonecode = 40; 
spherecode = 0;
projParm = zeros(1,13);
projParm(6) =  90000000;
gd.defProj(gridID,"ps",[],spherecode,projParm);
tileSize = [100 60];
gd.defTile(gridID,tileSize);
dimlist = {"XDim","YDim"};
gd.defField(gridID,"Pressure",dimlist,"int32");
for c = 0:2
    for r = 0:1
        data = (r+c)*ones(tileSize,"int32");
        gd.writeTile(gridID,"Pressure",[r c],data);
    end
end
gd.defTile(gridID,[]);
gd.detach(gridID);
gd.close(gfid);
