matlab.io.hdf4.sd.start

Namespace: matlab.io.hdf4.sd

Open HDF file and initialize SD interface

Syntax

sdID = start(filename)
sdID = start(filename,access)


Description

sdID = start(filename) opens the file filename in read-only mode. This routine must be called for each file before any other sd calls can be made on that file.

sdID = start(filename,access) opens the file filename with the access mode specified by access. This routine must be called before any other SD interface operations can be made on that file. Specify access as one of these values:

• 'read'

• 'write'

• 'create'

access defaults to 'read' if not supplied.

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

Examples

import matlab.io.hdf4.*
sdID = sd.start('sd.hdf');
sd.close(sdID);
