matlab.io.hdf4.sd.isCoordVar
Namespace: matlab.io.hdf4.sd
Determine if dataset is a coordinate variable
Syntax
TF = isCoordVar(sdsID)
Description
TF = isCoordVar(sdsID)
returns true
if a dataset is a
coordinate variable and returns false
otherwise.
This function corresponds to the SDiscoordvar
function
in the HDF library C API.
Examples
import matlab.io.hdf4.* sdID = sd.start('sd.hdf'); ndataset = sd.fileInfo(sdID); for idx = 0:ndataset-1 sdsID = sd.select(sdID,idx); sdsName = sd.getInfo(sdsID); fprintf('%s (index %d) ', sdsName, idx); if ( sd.isCoordVar(sdsID) ) fprintf('is a coordinate variable.\n'); else fprintf('is not a coordinate variable.\n'); end sd.endAccess(sdsID); end sd.close(sdID);
