Namespace: matlab.io.hdfeos.gd

Bilinear interpolation on a grid field

Syntax

data = interpolate(gridID,lat,lon,fieldname)


Description

data = interpolate(gridID,lat,lon,fieldname) performs bilinear interpolation on lat/lon pairs from the data in the grid field.

data contains the interpolated field values.

This function corresponds to the GDinterpolate function in the HDF-EOS library C API.

Examples

import matlab.io.hdfeos.*
gfid = gd.open('example.hdf');
gridID = gd.attach(gfid,'MonthlyRain');
[lat,lon] = gd.ij2ll(gridID,[18 18],[14 15]);
data = gd.interpolate(gridID,lat,lon,'TbOceanRain');
gd.detach(gridID);
gd.close(gfid);
