Namespace: matlab.io.hdfeos.gd

Read single tile of data from field

Syntax

data = readTile(gridID,fieldname,tileCoords)

Description

data = readTile(gridID,fieldname,tileCoords) reads a single of data from a field. If the data is to be read tile by tile, this routine is more efficient than gd.readField. In all other cases, use gd.readField. 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 GDreadtile 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('grid.hdf','read');
gridID = gd.attach(gfid,'PolarGrid');
for h = 0:9
    data = gd.readTile(gridID,'pressure',[0 0 h]);
end
gd.detach(gridID);
gd.close(gfid);
