Rename existing attribute
cdflib.renameAttr(cdfId,attrNum,newName)
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 character vector or string scalar that specifies the
name you want to assign to the attribute.
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
