Description

cdflib.setChecksum(cdfId,mode) specifies the checksum mode of a Common Data Format (CDF) file.

Input Arguments

cdfId

Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.

'NO_CHECKSUM'File does not use a checksum.

Examples

Create a CDF file and set the checksum mode. To run this example, you must be in a writable folder.

cdfid = cdflib.create('mycdf.cdf');

% Check initial value of checksum.
mode = cdflib.getChecksum(cdfid)

NO_CHECKSUM

cdflib.setChecksum(cdfid,'MD5_CHECKSUM')

% Verify the setting 
mode = cdflib.getChecksum(cdfid)
