cdflib.renameAttr - Rename existing attribute

Syntax

Description

cdflib.renameAttr(cdfId,attrNum,newName) renames an attribute in a Common Data Format (CDF) file.

cdfId identifies the CDF file. attrNum is a numeric value that identifies the attribute. Attribute numbers are zero-based. newName is a text string that specifies the name you want to assign to the attribute.

Examples

Create a CDF, create an attribute in the CDF, and then rename the attribute. To run this example, you must be in a writable folder.

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

% Create an attribute
attrNum = cdflib.createAttr(cdfid,'Purpose','global_scope');

% Rename the attribute
cdflib.renameAttr(cdfid, attrNum, 'NewPurpose');

% Check the name of the attribute
attrName = cdflib.getAttrName(cdfid,anum)

attrName =

NewPurpose

% Clean up
cdflib.delete(cdfid);

clear cdfid
