attrnum = cdflib.createAttr(cdfId,attrName,scope)
attrnum = cdflib.createAttr(cdfId,attrName,scope) creates an attribute in a CDF file with the specified scope.
Identifier of a CDF file, returned by a call to cdflib.create or cdflib.open.
Text string that specifies the name you want to assign to the attribute.
One of the following text strings, or its numeric equivalent, that specifies the scope of the attribute.
To get the numeric equivalent of these text string constants, use the cdflib.getConstantValue function.
Create a CDF, and then create an attribute in the CDF. To run this example, you must be in a writable folder.
cdfid = cdflib.create('your_file.cdf'); % Create attribute attrNum = cdflib.createAttr(cdfId,'Purpose','global_scope'); % Clean up cdflib.delete(cdfid); clear cdfid
This function corresponds to the CDF library C API routine CDFcreateAttr.
To use this function, you must be familiar with the CDF C interface. Read the CDF documentation at the CDF Web site.
