matlab.io.hdf4.sd.getDimID

Namespace: matlab.io.hdf4.sd

Dimension identifier

Syntax

dimID = getDimID(sdsID,dimnumber)

Description

dimID = getDimID(sdsID,dimnumber) returns the identifier of the dimension given its index.

Note

MATLAB® uses Fortran-style indexing while the HDF library uses C-style indexing. The order of the dimension identifiers retrieved with sd.getDimID are reversed from what would be retrieved via the C API.

This function corresponds to the SDgetdimid function in the HDF library C API.

Examples

Read an entire dataset.

import matlab.io.hdf4.*
sdID = sd.start('sd.hdf');
idx = sd.nameToIndex(sdID,'temperature');
sdsID = sd.select(sdID,idx);
dimID0 = sd.getDimID(sdsID,0);
dimID1 = sd.getDimID(sdsID,1);
sd.endAccess(sdsID);
sd.close(sdID);
