matlab.io.hdfeos.gd.fieldInfo

Namespace: matlab.io.hdfeos.gd

Information about data field

Syntax

[dims,ntype,dimlist] = fieldInfo(gridID,fieldname)

Description

[dims,ntype,dimlist] = fieldInfo(gridID,fieldname) returns information about a specific geolocation or data field in the grid. dims is a vector containing the dimension sizes of the field. ntype is a character vector or string scalar containing the HDF number type of the field. dimlist is a cell array of character vectors or a string array containing the dimension names.

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

Examples

import matlab.io.hdfeos.*
gfid = gd.open('grid.hdf','read');
gridID = gd.attach(gfid,'PolarGrid');
[dims,ntype,dimlist] = gd.fieldInfo(gridID,'ice_temp');
gd.detach(gridID);
gd.close(gfid);
